+The problem is the name clash between the library routine ©abs© and the \CFA names ©abs©.
+Hence, names appearing in an ©extern "C"© block have \newterm*{C linkage}.
 Then overloading polymorphism uses a mechanism called \newterm{name mangling}\index{mangling!name} to create unique names that are different from C names, which are not mangled.
 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}.
-The name ``�abs�'' evokes the notion of absolute value, and many mathematical types provide the notion of absolute value.

 The point of the new syntax is to allow returning multiple values from a routine~\cite{Galletly96,CLU}, \eg:

 Existing C syntax cannot be extended with multiple return types because it is impossible to embed a single routine name within multiple return type specifications.

 \Index*{Michael Tiemann}, with help from \Index*{Doug Lea}, provided named return values in g++, circa 1989.}
 The value of each local return variable is automatically returned at routine termination.
 Declaration qualifiers can only appear at the start of a routine definition, \eg:

 The inability to use \CFA declarations in these two contexts is probably a blessing because it precludes programmers from arbitrarily switching between declarations forms within a declaration contexts.
 
 C-style declarations can be used to declare parameters for \CFA style routine definitions, \eg:
 \begin{cfa}
-[ int ] f( * int, int * );			�\C{// returns an integer, accepts 2 pointers to integers}�
-[ * int, int * ] f( int );			�\C{// returns 2 pointers to integers, accepts an integer}�

+[ * int, int * ] f( int );			§\C{// returns 2 pointers to integers, accepts an integer}§
 \end{cfa}
 The reason for allowing both declaration styles in the new context is for backwards compatibility with existing preprocessor macros that generate C-style declaration-syntax, as in:
 \begin{cfa}
 #define ptoa( n, d ) int (*n)[ d ]
-int f( ptoa( p, 5 ) ) ...			�\C{// expands to int f( int (*p)[ 5 ] )}�
-[ int ] f( ptoa( p, 5 ) ) ...		�\C{// expands to [ int ] f( int (*p)[ 5 ] )}�

+[ int ] f( ptoa( p, 5 ) ) ...		§\C{// expands to [ int ] f( int (*p)[ 5 ] )}§
 \end{cfa}
 Again, programmers are highly encouraged to use one declaration form or the other, rather than mixing the forms.

 First the right-hand tuple is flattened and then the values are assigned individually.
 Flattening is also performed on tuple types.
-For example, the type �[ int, [ int, int ], int ]� can be coerced, using flattening, into the type �[ int, int, int, int ]�.
+For example, the type ©[ int, [ int, int ], int ]© can be coerced, using flattening, into the type ©[ int, int, int, int ]©.
 
 A \newterm{structuring coercion} is the opposite of flattening;
 a tuple is structured into a more complex nested tuple.
-For example, structuring the tuple �[ 1, 2, 3, 4 ]� into the tuple �[ 1, [ 2, 3 ], 4 ]� or the tuple type �[ int, int, int, int ]� into the tuple type �[ int, [ int, int ], int ]�.

 In the following example, the last assignment illustrates all the tuple coercions:
 \begin{cfa}
 [ int, int, int, int ] w = [ 1, 2, 3, 4 ];
 int x = 5;
-[ x, w ] = [ w, x ];		�\C{// all four tuple coercions}�

 Starting on the right-hand tuple in the last assignment statement, w is opened, producing a tuple of four values;
-therefore, the right-hand tuple is now the tuple �[ [ 1, 2, 3, 4 ], 5 ]�.
-This tuple is then flattened, yielding �[ 1, 2, 3, 4, 5 ]�, which is structured into �[ 1, [ 2, 3, 4, 5 ] ]� to match the tuple type of the left-hand side.
-The tuple �[ 2, 3, 4, 5 ]� is then closed to create a tuple value.
-Finally, �x� is assigned �1� and �w� is assigned the tuple value using multiple assignment (see Section 14).

 In C, the integer constants 0 and 1 suffice because the integer promotion rules can convert them to any arithmetic type, and the rules for pointer expressions treat constant expressions evaluating to 0 as a special case.
 However, user-defined arithmetic types often need the equivalent of a 1 or 0 for their functions or operators, polymorphic functions often need 0 and 1 constants of a type matching their polymorphic parameters, and user-defined pointer-like types may need a null value.
-Defining special constants for a user-defined type is more efficient than defining a conversion to the type from �_Bool�.
