    11\chapter{Background}
    22
    3 \CFA{} adds a number of features to C, some of them providing significant increases to the expressive power of the language, but all designed to maintain the existing procedural programming paradigm of C and to be as orthogonal as possible with each other.
    4 To provide background for the contributions in subsequent chapters, this chapter provides a summary of the features of \CFA{} at the time this work was conducted.
    5 
    6 The core design of \CFA{} is laid out in Glen Ditchfield's 1992 PhD thesis, \emph{Contextual Polymorphism}\cite{Ditchfield92}; in that thesis, Ditchfield lays out the theoretical underpinnings of the \CFA{} polymorphism model.
    7 Building on Ditchfield's design for contextual polymorphism as well as KW-C\cite{Buhr94a}, an earlier set of (largely syntactic) extensions to C, Richard Bilson\cite{Bilson03} built the first version of the \CFA{} compiler, \CFACC{}, in the early 2000's.
    8 This early \CFACC{} provided basic functionality, but incorporated a number of poor algorithmic choices due to a rushed implementation time frame, and as such lacked the runtime performance required for practical use; this thesis is substantially concerned with rectifying those deficits.
    9 
    10 The \CFA{} project was revived in 2015 with the intention of building a production-ready language and compiler; at the time of this writing, both \CFA{} and \CFACC{} have been under active development continuously since.
    11 As this development has been proceeding concurrently with the work described in this thesis, the state of \CFA{} has been somewhat of a moving target; however, Moss~\etal\cite{Moss18} provides a reasonable summary of the current design of \CFA{}.
    12 Notable features added during this period include generic types[Chapter~\ref{generic-chap}], constructors and destructors\cite{Schluntz17}, improved support for tuples\cite{Schluntz17}, reference types\cite{Moss18}, first-class concurrent and parallel programming support\cite{Delisle18}, as well as numerous pieces of syntactic sugar and the start of an idiomatic standard library\cite{Moss18}.
    13 
     3This is the background. Basically, need to cite Ditchfield\cite{Ditchfield92}, Bilson\cite{Bilson03}, and Moss~\etal\cite{Moss18}

    11\chapter{Introduction}
    22
    3 The C programming language has had a wide-ranging impact on the design of software and programming languages.
    4 In the 30 years since its first standardization, it has consistently been one of the most popular programming languages, with millions of lines of C code still in active use, and tens of thousands of trained programmers producing it. The TIOBE index\cite{TIOBE} tracks popularity of programming languages over time, and C has never dropped below second place:

    20 
    21 The impact of C on programming language design is also obvious from Table~\ref{tiobe-table}; with the exception of Python, all of the top five languages use C-like syntax and procedural control structures.
    22 \CC is even a largely backwards-compatible extension of C, with development dating back nearly as far as C itself.
    23 Though its lasting popularity and wide impact on programming language design point to the continued relevance of C, they also highlight the widespread desire of programmers for languages with more expressive power and programmer-friendly features; accommodating both low-impact maintenance of legacy C code and low-effort development of the software of the future is a difficult task for a single programming language.
    24 
    25 \CFA{}\footnote{Pronounced ``C-for-all'', and written \CFA{} or \CFL{}.} is an evolutionary modernization of the C programming language which aims to fulfill both these ends well.
    26 \CFA{} both fixes existing design problems and adds multiple new features to C, including name overloading, user-defined operators, parametric-polymorphic routines, and type constructors and destructors, among others.
    27 The new features make \CFA{} more powerful and expressive than C, while maintaining strong backward-compatibility with both C code and the procedural paradigm expected by C programmers.
    28 However, these new features do impose a compile-time cost, particularly in the expression resolver, which must evaluate the typing rules of a significantly more complex type-system.
    29 
    30 This thesis is focused on making \CFA{} a more powerful and expressive language, both by adding new features to the \CFA{} type system and ensuring that both added and existing features can be efficiently implemented in \CFACC{}, the \CFA{} reference compiler.
    31 Particular contributions of this work include design and implementation of
    32 parametric-polymorphic (``generic'') types in a manner compatible with the existing polymorphism design of \CFA{} (Chapter~\ref{generic-chap}), a type environment data structure based on a novel variant of the union-find algorithm (Chapter~\ref{env-chap}), and a new expression resolution algorithm designed to quickly locate the optimal declarations for a \CFA{} declaration (Chapter~\ref{resolution-chap}).
    33 This expression resolution algorithm was designed with the aid of a purpose-built prototype system which encapsulates the essential aspects of the \CFA{} type system without incurring the technical debt of the existing system or the friction-inducing necessity of maintaining a working compiler; the goal of this prototype system was to discover effective heuristics to avoid performing unnecessary work in the process of locating the optimal \CFA{} expression resolution.
    34 
    35 Though the direction and validation of this work was fairly narrowly focused on the \CFA{} programming language, the tools used and results obtained should be of interest to a wider compiler and programming language design community.
    36 In particular, with the addition of \emph{concepts} in \CCtwenty{}, conforming \CC{} compilers must support a model of type assertions very similar to that in \CFA{}, and the algorithmic techniques used in the expression resolution algorithm presented here may prove useful.
    37 Type environments are also widely modelled in compiler implementations, particularly of functional languages, though also increasingly commonly in other languages (such as Rust) which also perform type inference; the type environment presented here may be useful to those language implementers.
