Re: another take on hackers and painters

I'm glad you brought this up.  For those of us who aren't perl gurus, can
you please explain to us in as little space as possible how the hell perl
does this kind of thing?  Is the perl lexer/parser dynamically hackable or
something?  Would it be possible to write a scheme-like syntax for perl if
one was so inclined?  If not, where are the lines drawn?

I'm wondering if perl has the same kind of power as, say, ocamlp4 gives to
ocaml, or if it's doing something completely different.

Really curious,
