Just curious: Why would you want something like that? I thought that
the good thing(tm) about regular expressions is that they can be
parsed by a finite state machine rather than a recursive descent
parser, so for all I know, the C regular expression library that comes
with your system is most likely much faster than any Parsec code would
every be.

Not that I have tried it, though ...
