More as food for thought, given all the suggestions that we've had above, I know Damian was planning to rewrite Parse::RecDescent to handle complex code better, possibly having a Parse::Perl module that can parse and build a resulting tree structure for perl code. However, this latter project I believe was to be part of Perl 6 (I know I read it here on PM, but I cannot find the link). In any case, once we have a definitive parse tree for Perl, as opposed to relying on parenthesis matching, generating any structure for perl source will be rather simple.

It's not what you know, but knowing how to find it if you don't know that's important
