Sure. If you want to write a plugin that does it, keen.

Well, I think it'd be easier to write a proper C parser for perl. Or an APL
one. Heck, depending on what Larry does a Forth one might be easier. Perl 5
has a *lot* of little nooks in it that would require some special-case
code. (Besides, what exactly is perl 5 anyway? It's a rather poorly defined
thing) It's one of the reasons we're writing perl 6...

I doubt the parser will be all in perl for perl 6. Some maybe, and it will
likely use the regex engine, but I don't see it being all in perl. (And
yes, I know what Larry's said)
