Syntax extensions to ease TDD in racket (but I'll call it a new language!)

[Racket][] provides for unit testing (through the rackunit module). But there is no way to force functions to be tested. [Racket]: http://www.racket-lang.org

I'll only be able to "force" functions to be define/tested if I can suppress define.

TODO:

• define the define/tested syntax
• create a #lang the replaces (disables) define with define/tested
• create mock functions
• handle inner defines/named lets

As well as trying to produce something useful as a PLT Games entry, I'm also trying to learn: [syntax/parse][]. [syntax/parse]: http://docs.racket-lang.org/syntax/stxparse.html?q=syntax/parse
