Yeah, I should not even have mentioned regex. It was really meant as "if you really wanted to go wild, you could do something as crazy as regexes". But I agree that we would never want to pass regexes over the wire. If we want to make things more efficient, prefix-matching is the way. If we want to make things more ergonomic for the client-side user, then we should stick to globbing (which we already do, but we could do things like full-string globs rather than strict tail-matching). But I would hold off on all of that until somebody has a concrete case that shows why their preferred matching scheme is useful. -Peff
