Subject: Re: regular expressions

Not to get too ridiculous replying to myself here, but...

Regexps really aren't just regular expressions anymore; they are
considerably fancier and more powerful, so it's a bit of a misnomer.  (I
think.)

So how about this:

  Grammar.new {|g| 'a' + (g | '') + 'b'}

Matches n a's followed by n b's for all n... regexps can't do that.  (It's a
superset of regular expressions.)

Waddaya think, Hal?
