Hmm, it depends on what you want to do I guess: how would tell what index
those two sub-expressions were, or don't you care? It also means a complete
rewrite of the match_results interface, and probably the code that finds
matches as well - it all assumes that match_results is basically an array of
N sub-expressions.
