This is neat.  We should provide (something like) this in Text.Regex
itself, although perhaps the more generic regular expression
functionality should go somewhere like Data.Regex?

In any case, I'd be happy to add something to Text.Regex if you settle
on something you're happy with and send it to the list for comments.
