I would argue that if somebody does that, they're just broken.

The single level of recursion is really nice - it solves a real annoyance.
But if somebody starts trying to do multiple levels, that's just crazy.

Of course, I guess we don't relly have any way of sanely _counting_ the
recursion level, so we'd have to just trust people to not do crazy things.

And that's a big thing to take on trust ;)
