Devel::Declare

Here's a little module Dave Rolsky turned me onto - I'm going to have to read it a couple of times, but essentially it takes control of the Perl parser by arcane means and lets you define your own syntax.

I love the idea of getting away from rickety code generation and into rickety on-the-fly code munging, but the real value would be letting the Perl parser do what it does best; trying to fake it with line-by-line regexps is just asking for trouble.
