I think perl6 is definitely the way to go, once it's ready. BTW, what's the deal with Bundle::Perl6? I tried installing it from cpan yesterday but it wouldn't install with my perl.

Well the "new language" was just for the imcc code templates. Now I think the better path is to define a code-generating class for each ast node. Then PythonWhileNode can be a subclass of the generic WhileNode.

Yep. For now, everything pypirate generates *is* pmc based, since python doesn't have type declarations. Generic pirate should probably have a "declare" node though. (Especially if it's to handle perl6, right?)
