awesome.

A correction: I know of no reason why heckle shouldn't work on windows.

No, none. Just haven't even tried and it hasn't been a really big priority for me. :)

Currently I'm working on 2 things:

1) Removing as many extraneous nodes from ParseTree/ruby_parser's output as I can (eg, no more scope/block in defn, no more arglist in call).
2) A complete rewrite of ruby_parser (separate from the above) to be LL.

As such, other stuff has fallen by the wayside.
