Is something like B::Generate is what you are looking for? e.g. see:
http://www.perl.com/pub/a/2002/05/07/optree.html

Simon had an interesting paper in the last OSC's proceeding paper. I 
don't know if it's available online. It was called:
   B::Generate + Source Filters = use Python;

In any case you probably want to move this discussion to some other perl 
specific list/forum, unless it has something to do with mod_perl.
