Have you considered Regexp::Comment?
CPAN - there's something there for everyone!
Doh! I really should slow down and read more carefully! I suggested that he try something he's already tried.... my bad. Sorry.
He states in his post that he has, and it does not work exactly how he wants it to. I would say to expand that module to the point that it works for your needs and then send a diff back to the author of the changes you make so as to let them decide if any of your mods warrent inclusion in the module.
