 The resolver prototype presented in this work has good performance and already has the basics of \CFA{} semantics implemented, as well as many of the necessary core data structures, and would be a viable candidate for a new compiler architecture. 
 An alternate approach would be to fork an existing C compiler such as Clang~\cite{Clang}, which would need to be modified to use one of the resolution algorithms discussed here, as well as various other features introduced by Bilson~\cite{Bilson03}.
+
+More generally, the algorithmic techniques described in this thesis may be useful to implementors of other programming languages. 
+In particular, the demonstration of practical performance for polymorphic return-type inference suggests the possibility of eliding return-type-only template parameters in \CC{} function calls, though integrating such an extension into \CC{} expression resolution in a backwards-compatible manner may be challenging. 
+The \CFA{} expression resolution problem also bears some similarity to the \emph{local type inference} model put forward by Pierce \& Turner \cite{Pierce00} and Odersky \etal{} \cite{Odersky01}; compiler implementors for languages such as Scala \cite{Scala} that perform type inference based on this model may be able to profitably adapt the algorithms and data structures presented in this thesis.

 \CFACC{} can generate realistic test inputs for the resolver prototype from equivalent \CFA{} code; 
-the generated test inputs currently comprise all \CFA{} code currently in existence, $9,000$ lines drawn primarily from the standard library and compiler test suite. 
+the generated test inputs currently comprise all \CFA{} code currently in existence, 9,000 lines drawn primarily from the standard library and compiler test suite. 
 \CFACC{} is also instrumented to produce a number of code metrics. 
 These metrics were used to construct synthetic test inputs during development of the resolver prototype; these synthetic inputs provided useful design guidance, but the performance results presented in this chapter are based on the more realistic directly-generated inputs.
