If you have the 2nd edition of the pick-axe book, in chapter 22,
there's a section called "Variables and Constants" which give a slew
of variables.

I don't want to type them all in.  But it looks like you're after
either $&, which provides the matching string, or $~, which provides
the MatchData object that describes the match.
