intertwingly

I'm putting this out here so that people can poke fun at it.  It is totally TDD, and YAGNI.  In fact, the only portion that has had more than a few moments of thought put into it is in the ast.__init__ source file.

I'm totally impressed by Michal's Pirate, in a put everything in one source file as the author has the whole problem in his head sort of way.

What I would like to see is a refactoring so that blocks of code are objects which understand their own symbol tables.  My goal is to implement patterns which reflect how a human coder would chose to implement something in Parrot.
