 Proposal for virtual functionality
+There are two types of virtual inheritance in this proposal, relaxed
+(implicit) and strict (explicit). Relaxed is the simpler case that uses the
+existing trait system with the addition of trait references and vtables.
+Strict adds some constraints and requires some additional notation but allows
+for down-casting.
+Relaxed Virtual Inheritance:
 Imagine the following code :
 …
 void draw(line*);
 While all the members of this simple UI support drawing creating a UI that easily
 supports both these UI requires some tedious boiler-plate code :
+While all the members of this simple UI support drawing, creating a UI that
+easily supports both these UI requires some tedious boiler-plate code:
 enum type_t { text, line };
 …
+}
+While this code will work as indented, adding any new widgets or any new widget behaviors
+requires changing existing code to add the desired functionality. To ease this maintenance
+effort required CFA introduces the concept of dynamic types, in a manner similar to C++.
+A simple usage of dynamic type with the previous example would look like :
+drawable* objects[10];
+While this code will work as implemented, adding any new widgets or any new
+widget behaviors requires changing existing code to add the desired
+functionality. To ease this maintenance effort required CFA introduces the
+concept of trait references.
+Using trait references to implement the above gives the following :
+trait drawable objects[10];
 fill_objects(objects);
 while(running) {
       for(drawable* object : objects) {
+      for(drawable object : objects) {
             draw(object);
+      }
+}
+However, this is not currently do-able in the current CFA and furthermore is not
+possible to implement statically. Therefore we need to add a new feature to handle
+having dynamic types like this (That is types that are found dynamically not types
+that change dynamically).
+C++ uses inheritance and virtual functions to find the
+desired type dynamically. CFA takes inspiration from this solution.
+What we really want to do is express the fact that calling draw() on a object
+should find the dynamic type of the parameter before calling the routine, much like the
+hand written example given above. We can express this by adding the virtual keyword on
+the parameter of the constraints on our trait:
+The keyword trait is optional (by the same rules as the struct keyword). This
+is not currently supported in CFA and the lookup is not possible to implement
+statically. Therefore we need to add a new feature to handle having dynamic
+lookups like this.
+What we really want to do is express the fact that calling draw() on a trait
+reference should find the underlying type of the given parameter and find how
+it implements the routine, as in the example with the enumeration and union.
+For instance specifying that the drawable trait reference looks up the type
+of the first argument to find the implementation would be :
 trait drawable(otype T) {
 …
 };
+This expresses the idea that drawable is similar to an abstract base class in C++ and
+also gives meaning to trying to take a pointer of drawable. That is anything that can
+be cast to a drawable pointer has the necessary information to call the draw routine on
+that type. Before that drawable was only a abstract type while now it also points to a
+piece of storage which specify which behavior the object will have at run time.
+This storage needs to be allocate somewhere. C++ just adds an invisible pointer at
+the beginning of the struct but we can do something more explicit for users, actually
+have a visible special field :
+struct text {
+      char* text;
+      vtable drawable;
+};
+struct line{
+      vtable drawable;
+      vec2 start;
+      vec2 end;
+};
+With these semantics, adding a "vtable drawable" means that text pointers and line pointers are now
+convertible to drawable pointers. This conversion will not necessarily be a type only change however, indeed,
+the drawable pointer will point to the field "vtable drawable" not the head of the struct. However, since all
+the types are known at compile time, converting pointers becomes a simple offset operations.
+The vtable field contains a pointer to a vtable which contains all the information needed for the caller
+to find the function pointer of the desired behavior.
+One of the limitations of this design is that it does not support double dispatching, which
+concretely means traits cannot have routines with more than one virtual parameter. This design
+would have many ambiguities if it did support multiple virtual parameter. A futher limitation is
+that traits over more than one type cannot have vtables meaningfully defined for them, as the
+particular vtable to use would be a function of the other type(s) the trait is defined over.
+It is worth noting that the function pointers in these vtables are bound at object construction, rather than
+function call-site, as in Cforall's existing polymorphic functions. As such, it is possible that two objects
+with the same static type would have a different vtable (consider what happens if draw(line*) is overridden
+between the definitions of two line objects). Given that the virtual drawable* erases static types though,
+this should not be confusing in practice. A more distressing possibility is that of creating an object that
+outlives the scope of one of the functions in its vtable. This is certainly a possible bug, but it is of a
+type that C programmers are familiar with, and should be able to avoid by the usual methods.
+Extensibility.
+One of the obvious critics of this implementation is that it lacks extensibility for classes
+that cannot be modified (ex: Linux C headers). However this solution can be extended to
+allow more extensibility by adding "Fat pointers".
+Indeed, users could already "solve" this issue by writing their own fat pointers as such:
+trait MyContext(otype T) {
+      void* get_stack(virtual T*)
+};
+void* get_stack(ucontext_t *context);
+struct fat_ucontext_t {
+      vtable MyContext;
+      ucontext_t *context;
+}
+//Tedious forwarding routine
+void* get_stack(fat_ucontext_t *ptr) {
+      return get_stack(ptr->context);
+}
+However, users would have to write all the virtual methods they want to override and make
+them all simply forward to the existing method that takes the corresponding POCO(Plain Old C Object).
+The alternative we propose is to use language level fat pointers :
+trait MyContext(otype T) {
+      void* get_stack(virtual T*)
+};
+void* get_stack(ucontext_t *context);
+//The type vptr(ucontext_t) all
+vptr(ucontext_t) context;
+These behave exactly as the previous example but all the forwarding routines are automatically generated.
+Bikeshedding.
+It may be desirable to add fewer new keywords than discussed in this proposal; it is possible that "virtual"
+could replace both "vtable" and "vptr" above with unambiguous contextual meaning. However, for purposes of
+clarity in the design discussion it is beneficial to keep the keywords for separate concepts distinct.
+This could be implied in simple cases like this one (single parameter on the
+trait and single generic parameter on the function). In more complex cases it
+would have to be explicitly given, or a strong convention would have to be
+enforced (e.g. implementation of trait functions is always drawn from the
+first polymorphic parameter).
+Once a function in a trait has been marked as virtual it defines a new
+function that takes in that trait's reference and then dynamically calls the
+underlying type implementation. Hence a trait reference becomes a kind of
+abstract type, cannot be directly instantiated but can still be used.
+One of the limitations of this design is that it does not support double
+dispatching, which concretely means traits cannot have routines with more than
+one virtual parameter. The program must have a single table to look up the
+function on. Using trait references with traits with more than one parameter
+is also restricted, initially forbidden, see extension.
+Extension: Multi-parameter Virtual Traits:
+This implementation can be extended to traits with multiple parameters if
+one is called out as being the virtual trait. For example :
+trait iterator(otype T, dtype Item) {
+        Maybe(Item) next(virtual T *);
+}
+iterator(int) generators[10];
+Which creates a collection of iterators that produce integers, regardless of
+how those iterators are implemented. This may require a note that this trait
+is virtual on T and not Item, but noting it on the functions may be enough.
+Strict Virtual Inheritance:
+One powerful feature relaxed virtual does not support is the idea of down
+casting. Once something has been converted into a trait reference there is
+very little we can do to recover and of the type information, only the trait's
+required function implementations are kept.
+To allow down casting strict virtual requires that all traits and structures
+involved be organized into a tree. Each trait or struct must have a unique
+position on this tree (no multiple inheritance).
+This is declared as follows :
+trait error(otype T) virtual {
+        const char * msg(T *);
+}
+trait io_error(otype T) virtual error {
+        FILE * src(T *);
+}
+struct eof_error virtual io_error {
+        FILE * fd;
+};
+So the trait error is the head of a new tree and io_error is a child of it.
+Also the parent trait is implicitly part of the assertions of the children,
+so all children implement the same operations as the parent. By the unique
+path down the tree, we can also uniquely order them so that a prefix of a
+child's vtable has the same format as its parent's.
+This gives us an important extra feature, runtime checking of the parent-child
+relationship with a C++ dynamic_cast like operation. Allowing checked
+conversions from trait references to more particular references, which works
+if the underlying type is, or is a child of, the new trait type.
+Extension: Multiple Parents
+Although each trait/struct must have a unique position on each tree, it could
+have positions on multiple trees. All this requires is the ability to give
+multiple parents, as here :
+trait region(otype T) virtual drawable, collider;
+The restriction being, the parents must come from different trees. This
+object (and all of its children) can be cast to either tree. This is handled
+by generating a separate vtable for each tree the structure is in.
+Extension: Multi-parameter Strict Virtual
+If a trait has multiple parameters then one must be called out to be the one
+we generate separate vtables for, as in :
+trait example(otype T, otype U) virtual(T) ...
+This can generate a separate vtable for each U for which all the T+U
+implementations are provided. These are then separate nodes in the tree (or
+the root of different trees) as if each was created individually. Providing a
+single unique instance of these nodes would be the most difficult aspect of
+this extension, possibly intractable, though with sufficient hoisting and
+link-once duplication it may be possible.
+Example:
+trait argument(otype T) virtual {
+        char short_name(virtual T *);
+        bool is_set(virtual T *);
+};
+trait value_argument(otype T, otype U) virtual(T) argument {
+        U get_value(virtual T *);
+};
+Extension: Structural Inheritance
+Currently traits must be the internal nodes and structs the leaf nodes.
+Structs could be made internal nodes as well, in which case the child structs
+would likely structurally inherit the fields of their parents.
+Storing the Virtual Lookup Table (vtable):
+We have so far been silent on how the vtable is created, stored and accessed.
+Creation happens at compile time. Function pointers are found by using the
+same best match rules as elsewhere (additional rules for defaults from the
+parent may or may not be required). For strict virtual this must happen at the
+global scope and forbidding static functions, to ensure that a single unique
+vtable is created. Similarly, there may have to be stricter matching rules
+for the functions that go into the vtable, possibly requiring an exact match.
+Relaxed virtual could relax both restrictions, if we allow different vtable
+at different conversion (struct to trait reference) sites. If it is allowed
+local functions being bound to a vtable could cause issues when they go out
+of scope, however this should follow the lifetime rules most C programs
+already follow implicitly.
+Most vtables should be stored statically, the only exception being some of
+the relaxed vtables that could have local function pointers. These may be able
+to be stack allocated. All vtables should be immutable and require no manual
+cleanup.
+Access has two main options:
+The first is through the use of fat pointers, or a tuple of pointers. When the
+object is converted to a trait reference, the pointers to its vtables are
+stored along side it.
+This allows for compatibility with existing structures (such as those imported
+from C) and is the default storage method unless a different one is given.
+The other is by inlining the vtable pointer as "intrusive vtables". This adds
+a field to the structure to the vtable. The trait reference then has a single
+pointer to this field, the vtable includes an offset to find the beginning of
+the structure again.
+This is used if you specify a vtable field in the structure. If given in the
+trait the vtable pointer in the trait reference can then become a single
+pointer to the vtable field and use that to recover the original object
+pointer as well as retrieve all operations.
+trait drawable(otype T) {
+        vtable drawable;
+};
+struct line {
+        vtable drawable;
+        vec2 start;
+        vec2 end;
+};
+This inline code allows trait references to be converted to plain pointers
+(although they still must be called specially). The vtable field may just be
+an opaque block of memory or it may allow user access to the vtable. If so
+then there should be some way to retrieve the type of the vtable, which will be
+autogenerated and often unique.
+Keyword Usage:
+It may be desirable to add fewer new keywords than discussed in this proposal.
+It is possible that "virtual" could replace both "vtable" above with
+unambiguous contextual meaning. However, for purposes of clarity in the design
+discussion it is beneficial to keep the keywords for separate concepts distinct.
+Trait References and Operations:
+sizeof(drawable) will return the size of the trait object itself. However :
+line a_line;
+drawable widget = a_line;
+sizeof(widget);
+Will instead return the sizeof the underlying object, although the trait must
+require that its implementation is sized for there to be a meaningful value
+to return. You may also get the size of the trait reference with
+sizeof(&widget);
+Calling free on a trait reference will free the memory for the object. It will
+leave the vtables alone, as those are (always?) statically allocated.

 \CFA{}\index{cforall@\CFA}\footnote{Pronounced ``\Index*{C-for-all}'', and written \CFA, CFA, or \CFL.} is a modern general-purpose programming-language, designed as an evolutionary step forward for the C programming language.
 The syntax of the \CFA language builds from C, and should look immediately familiar to C/\Index*[C++]{\CC{}} programmers.
+The syntax of \CFA builds from C and should look immediately familiar to C/\Index*[C++]{\CC{}} programmers.
 % Any language feature that is not described here can be assumed to be using the standard \Celeven syntax.
 \CFA adds many modern programming-language features that directly lead to increased \emph{\Index{safety}} and \emph{\Index{productivity}}, while maintaining interoperability with existing C programs and achieving C performance.
 Like C, \CFA is a statically typed, procedural language with a low-overhead runtime, meaning there is no global \Index{garbage-collection}, but \Index{regional garbage-collection}\index{garbage-collection!regional} is possible.
+\CFA adds many modern programming-language features that directly lead to increased \emph{\Index{safety}} and \emph{\Index{productivity}}, while maintaining interoperability with existing C programs and achieving similar performance.
+Like C, \CFA is a statically typed, procedural (non-\Index{object-oriented}) language with a low-overhead runtime, meaning there is no global \Index{garbage-collection}, but \Index{regional garbage-collection}\index{garbage-collection!regional} is possible.
 The primary new features include parametric-polymorphic routines and types, exceptions, concurrency, and modules.
+One of the main design philosophies of \CFA is to ``describe not prescribe'', which means \CFA tries to provide a pathway from low-level C programming to high-level \CFA programming, but it does not force programmers to ``do the right thing''.
+Programmers can cautiously add \CFA extensions to their C programs in any order and at any time to incrementally move towards safer, higher-level programming features.
+A programmer is always free to reach back to C from \CFA for any reason, and in many cases, new \CFA features have a fallback to a C mechanism.
+There is no notion or requirement for rewriting a legacy C program in \CFA;
+instead, a programmer evolves an existing C program into \CFA by incrementally incorporating \CFA features.
+New programs can be written in \CFA using a combination of C and \CFA features.
+\Index*[C++]{\CC{}} had a similar goal 30 years ago, but currently has the disadvantages of multiple legacy design-choices that cannot be updated and active divergence of the language model from C, requiring significant effort and training to incrementally add \CC to a C-based project.

+\subsection{Background}
 This document is a programmer reference-manual for the \CFA programming language.
 The manual covers the core features of the language and runtime-system, with simple examples illustrating syntax and semantics of each feature.
 The manual does not teach programming, i.e., how to combine the new constructs to build complex programs.
 A reader should already have an intermediate knowledge of control flow, data structures, and concurrency issues to understand the ideas presented as well as some experience programming in C/\CC.
 Implementers may refer to the \CFA Programming Language Specification for details about the language syntax and semantics.

 This installation base and the programmers producing it represent a massive software-engineering investment spanning decades and likely to continue for decades more.
 Even with all its problems, C continues to be popular because it allows writing software at virtually any level in a computer system without restriction.
 For system programming, where direct access to hardware and dealing with real-time issues is a requirement, C is usually the language of choice.
+For system programming, where direct access to hardware, storage management, and real-time issues are a requirement, C is usually the only language of choice.
 The TIOBE index~\cite{TIOBE} for March 2016 showed the following programming-language popularity: \Index*{Java} 20.5\%, C 14.5\%, \Index*[C++]{\CC{}} 6.7\%, \Csharp 4.3\%, \Index*{Python} 4.3\%, where the next 50 languages are less than 3\% each with a long tail.
 As well, for 30 years, C has been the number 1 and 2 most popular programming language:

 \end{center}
 Hence, C is still an extremely important programming language, with double the usage of \Index*[C++]{\CC{}}; in many cases, \CC is often used solely as a better C.
 Love it or hate it, C has been an important and influential part of computer science for 40 years and sit appeal is not diminishing.
 Unfortunately, C has too many problems and omissions to make it an acceptable programming language for modern needs.
 As stated, the goal of the \CFA project is to engineer modern language features into C in an evolutionary rather than revolutionary way.

 These languages have different syntax and semantics from C, and do not interoperate directly with C, largely because of garbage collection.
+These languages have different syntax and semantics from C, do not interoperate directly with C, and are not systems languages because of restrictive memory-management or garbage collection.
 As a result, there is a significant learning curve to move to these languages, and C legacy-code must be rewritten.
 These costs can be prohibitive for many companies with a large software base in C/\CC, and a significant number of programmers requiring retraining to a new programming language.
 The result of this project is a language that is largely backwards compatible with \Index*[C11]{\Celeven{}}~\cite{C11}, but fixing some of the well known C problems and containing many modern language features.

 as a result, it will fade into disuse.
 Considering the large body of existing C code and programmers, there is significant impetus to ensure C is transformed into a modern programming language.
 While \Index*[C11]{\Celeven{}} made a few simple extensions to the language, nothing was added to address existing problems in the language or to augment the language with modern language features.
 While some may argue that modern language features may make C complex and inefficient, it is clear a language without modern capabilities is insufficient for the advanced programming problems existing today.

 \section{History}
 The \CFA project started with \Index*{K-W C}~\cite{Buhr94a,Till89}, which extended C with new declaration syntax, multiple return values from routines, and extended assignment capabilities using the notion of tuples.

 However, at that time, there was little interesting in extending C, so work did not continue.

 \CFA is designed to integrate directly with existing C programs and libraries.

+The most important feature of \Index{interoperability} is using the same \Index{calling convention}s, so there is no complex interface or overhead to call existing C routines.
 This feature allows \CFA programmers to take advantage of the existing panoply of C libraries to access thousands of external software features.
 Language developers often state that adequate \Index{library support} takes more work than designing and implementing the language itself.
 Fortunately, \CFA, like \Index*[C++]{\CC{}}, starts with immediate access to all exiting C libraries, and in many cases, can easily wrap library routines with simpler and safer interfaces, at very low cost.
 Hence, \CFA begins by leveraging the large repository of C libraries with little cost.

 However, it is necessary to differentiate between C and \CFA code because of name overloading, as for \CC.
+However, it is necessary to differentiate between C and \CFA code because of name \Index{overload}ing, as for \CC.
 For example, the C math-library provides the following routines for computing the absolute value of the basic types: ©abs©, ©labs©, ©llabs©, ©fabs©, ©fabsf©, ©fabsl©, ©cabsf©, ©cabs©, and ©cabsl©.
 Whereas, \CFA wraps each of these routines into ones with the common name ©abs©:
+Whereas, \CFA wraps each of these routines into ones with the overloaded name ©abs©:
 \begin{cfa}
 char abs( char );
+®extern "C" {®
+int abs( int );                                                 §\C{// use default C routine for int}§
+®}® // extern "C"
+®extern "C" {® int abs( int ); ®}®              §\C{// use default C routine for int}§
 long int abs( long int );
 long long int abs( long long int );
 …
 Hence, there is the same need as in \CC, to know if a name is a C or \CFA name, so it can be correctly formed.
 There is no way around this problem, other than C's approach of creating unique names for each pairing of operation and type.
+This example strongly illustrates a core idea in \CFA: \emph{the power of a name}.
+This example strongly illustrates a core idea in \CFA: \emph{the \Index{power of a name}}.
 The name ``©abs©'' evokes the notion of absolute value, and many mathematical types provide the notion of absolute value.
 Hence, knowing the name ©abs© should be sufficient to apply it to any type where it is applicable.
 The time savings and safety of using one name uniformly versus $N$ unique names should not be underestimated.

 While C provides ©continue© and ©break© statements for altering control flow, both are restricted to one level of nesting for a particular control structure.
 Unfortunately, this restriction forces programmers to use \Indexc{goto} to achieve the equivalent control-flow for more than one level of nesting.
 To prevent having to switch to the ©goto©, \CFA extends the \Indexc{continue}\index{continue@\lstinline $continue$!labelled}\index{labelled!continue@©continue©} and \Indexc{break}\index{break@\lstinline $break$!labelled}\index{labelled!break@©break©} with a target label to support static multi-level exit\index{multi-level exit}\index{static multi-level exit}~\cite{Buhr85,Java}.

 The advantage of the labelled ©continue©/©break© is allowing static multi-level exits without having to use the ©goto© statement, and tying control flow to the target control structure rather than an arbitrary point in a program.
 Furthermore, the location of the label at the \emph{beginning} of the target control structure informs the reader that complex control-flow is occurring in the body of the control structure.

 Finally, using an explicit target for the transfer instead of an implicit target allows new constructs to be added or removed without affecting existing constructs.

 \section{Switch Statement}
+\section{\texorpdfstring{\LstKeywordStyle{switch} Statement}{switch Statement}}
 C allows a number of questionable forms for the ©switch© statement:
 …
         ®// open input file
 ®} else if ( argc == 2 ) {
         ®// open input file
+        ®// open input file (duplicate)
 ®} else {
 …
 \begin{cfa}
 switch ( i ) {
   case 1: case 3: case 5:       // odd values
         // same action
+  ®case 1: case 3: case 5:®     // odd values
+        // odd action
         break;
   case 2: case 4: case 6:       // even values
         // same action
+  ®case 2: case 4: case 6:®     // even values
+        // even action
         break;
+}
 …
 However, this situation is handled in other languages without fall-through by allowing a list of case values.
 While fall-through itself is not a problem, the problem occurs when fall-through is the default, as this semantics is unintuitive to many programmers and is different from virtually all other programming languages with a ©switch© statement.
 Hence, default fall-through semantics results in a large number of programming errors as programmers often forget the ©break© statement at the end of a ©case© clause, resulting in inadvertent fall-through.

 The problem with this usage is branching into control structures, which is known to cause both comprehension and technical difficulties.
 The comprehension problem occurs from the inability to determine how control reaches a particular point due to the number of branches leading to it.
+The technical problem results from the inability to ensure allocation and initialization of variables when blocks are not entered at the beginning.
+Often transferring into a block can bypass variable declaration and/or its initialization, which results in subsequent errors.
+There are virtually no positive arguments for this kind of control flow, and therefore, there is a strong impetus to eliminate it.

 and there is only a medium amount of fall-through from one ©case© clause to the next, and most of these result from a list of case values executing common code, rather than a sequence of case actions that compound.

 Like the ©switch© statement, the ©choose© statement retains the fall-through semantics for a list of ©case© clauses;
 the implicit ©break© is applied only at the end of the \emph{statements} following a ©case© clause.
 The explicit ©fallthru© is retained because it is a C-idiom most C programmers expect, and its absence might discourage programmers from using the ©choose© statement.

 \section{Case Clause}

 C restricts the ©case© clause of a ©switch© statement to a single value.
 …
+\section{\texorpdfstring{\LstKeywordStyle{with} Clause / Statement}{with Clause / Statement}}
+\label{s:WithClauseStatement}
+In \Index{object-oriented} programming, there is an implicit first parameter, often names \textbf{©self©} or \textbf{©this©}, which is elided.
+\begin{C++}
+class C {
+        int i, j;
+        int mem() {              ®// implicit "this" parameter
+®               i = 1;          ®// this->i
+®               j = 3;          ®// this->j
+®       }
+}
+\end{C++}
+Since CFA is non-object-oriented, the equivalent object-oriented program looks like:
+\begin{cfa}
+struct S { int i, j; };
+int mem( S &this ) {    // explicit "this" parameter
+        ®this.®i = 1;                     // "this" is not elided
+        ®this.®j = 2;
+}
+\end{cfa}
+but it is cumbersome having to write "©this.©" many times in a member.
+\CFA provides a ©with© clause/statement (see Pascal~\cite[\S~4.F]{Pascal}) to elided the "©this.©" by opening a scope containing field identifiers, changing the qualified fields into variables and giving an opportunity for optimizing qualified references.
+\begin{cfa}
+int mem( S &this ) ®with this® {        // with clause
+        i = 1;                  ®// this.i
+®       j = 2;                  ®// this.j
+®}
+\end{cfa}
+which extends to multiple routine parameters:
+\begin{cfa}
+struct T { double m, n; };
+int mem2( S &this1, T &this2 ) ®with this1, this2® {
+        i = 1; j = 2;
+        m = 1.0; n = 2.0;
+}
+\end{cfa}
+The statement form is used within a block:
+\begin{cfa}
+int foo() {
+        struct S1 { ... } s1;
+        struct S2 { ... } s2;
+        ®with s1® {                     // with statement
+                // access fields of s1 without qualification
+                ®with s2® {  // nesting
+                        // access fields of s1 and s2 without qualification
+                }
+        }
+        ®with s1, s2® {
+                // access unambiguous fields of s1 and s2 without qualification
+        }
+}
+\end{cfa}
+When opening multiple structures, fields with the same name and type are ambiguous and must be fully qualified.
+For fields with the same name but different type, context/cast can be used to disambiguate.
+\begin{cfa}
+struct S { int i; int j; double m; } a, c;
+struct T { int i; int k; int m } b, c;
+®with a, b® {
+        j + k;                                          §\C{// unambiguous, unique names define unique types}§

 \section{Exception Handling}
+\label{s:ExceptionHandling}
 Exception handling provides two mechanism: change of control flow from a raise to a handler, and communication from the raise to the handler.
+\begin{cfa}
+exception void h( int i );
+exception int h( int i, double d );
+Transfer of control can be local, within a routine, or non-local, among routines.
+Non-local transfer can cause stack unwinding, i.e., non-local routine termination, depending on the kind of raise.
+\begin{cfa}
+exception_t E {};                               §\C{// exception type}§
 void f(...) {
+        ... throw h( 3 );
+        ... i = resume h( 3, 5.1 );
+}
+        ... throw E{}; ...                      §\C{// termination}§
+        ... throwResume E{}; ...        §\C{// resumption}§
+}
 try {
         f(...);
 } catch h( int w ) {
         // reset
 } resume h( int p, double x ) {
         return 17;  // recover
+} catch( E e : §boolean-predicate§ ) {                  §\C{// termination handler}§
+        // recover and continue
+} catchResume( E e : §boolean-predicate§ ) {    §\C{// resumption handler}§
+        // repair and return
 } finally {
+}
+\end{cfa}
+So the type raised would be the mangled name of the exception prototype and that name would be matched at the handler clauses by comparing the strings.
+The arguments for the call would have to be packed in a message and unpacked at handler clause and then a call made to the handler.
+        // always executed
+}
+\end{cfa}
+The kind of raise and handler match: ©throw© with ©catch© and ©throwResume© with ©catchResume©.
+Then the exception type must match along with any additonal predicate must be true.
+The ©catch© and ©catchResume© handlers may appear in any oder.
+However, the ©finally© clause must appear at the end of the ©try© statement.

+\section{Pointer/Reference}
+\section{Exponentiation Operator}
+C, \CC, and Java (and many other programming languages) have no exponentiation operator\index{exponentiation!operator}\index{operator!exponentiation}, \ie $x^y$, and instead use a routine, like \Indexc{pow}, to perform the exponentiation operation.
+\CFA extends the basic operators with the exponentiation operator ©?\?©\index{?\\?@\lstinline$?\?$} and ©?\=?©\index{?\\=?@\lstinline$?\=?$}, as in, ©x \ y© and ©x \= y©, which means $x^y$ and $x \leftarrow x^y$.
+The priority of the exponentiation operator is between the cast and multiplicative operators, so that ©w * (int)x \ (int)y * z© is parenthesized as ©((w * (((int)x) \ ((int)y))) * z)©.
+As for \Index{division}, there are exponentiation operators for integral and floating-point types, including the builtin \Index{complex} types.
+Unsigned integral exponentiation\index{exponentiation!unsigned integral} is performed with repeated multiplication (or shifting if the base is 2).
+Signed integral exponentiation\index{exponentiation!signed integral} is performed with repeated multiplication (or shifting if the base is 2), but yields a floating-point result because $b^{-e}=1/b^e$.
+Hence, it is important to designate exponent integral-constants as unsigned or signed: ©3 \ 3u© return an integral result, while ©3 \ 3© returns a floating-point result.
+Floating-point exponentiation\index{exponentiation!floating point} is performed using \Index{logarithm}s\index{exponentiation!logarithm}, so the base cannot be negative.
+\begin{cfa}
+sout | 2 ®\® 8u | 4 ®\® 3u | -4 ®\® 3u | 4 ®\® -3 | -4 ®\® -3 | 4.0 ®\® 2.1 | (1.0f+2.0fi) ®\® (3.0f+2.0fi) | endl;
+64 -64 0.015625 -0.015625 18.3791736799526 0.264715-1.1922i
+\end{cfa}
+Parenthesis are necessary for the complex constants or the expresion is parsed as ©1.0f+(2.0fi \ 3.0f)+2.0fi©.
+The exponentiation operator is available for all the basic types, but for user-defined types, only the integral-computation versions are available.
+For returning an integral value, the user type ©T© must define multiplication, ©*©, and one, ©1©;
+for returning a floating-point value, an additional divide of type ©T© into a ©double© returning a ©double© (©double ?/?( double, T )©) is necessary for negative exponents.
+\section{Pointer / Reference}
 C provides a \newterm{pointer type};
 …
 An integer constant expression with the value 0, or such an expression cast to type ©void *©, is called a \newterm{null-pointer constant}.\footnote{
 One way to conceptualize the null pointer is that no variable is placed at this address, so the null-pointer address can be used to denote an uninitialized pointer/reference object;
+\ie the null pointer is guaranteed to compare unequal to a pointer to any object or routine.}
+\ie the null pointer is guaranteed to compare unequal to a pointer to any object or routine.
+In general, a value with special meaning among a set of values is called a \emph{\Index{sentinel value}}, \eg ©-1© as a return code value.}
 An address is \newterm{sound}, if it points to a valid memory location in scope, \ie within the program's execution-environment and has not been freed.
 Dereferencing an \newterm{unsound} address, including the null pointer, is \Index{undefined}, often resulting in a \Index{memory fault}.
