I guess the question is: is this a thing we would want to make available to code to leave in all the time? Or is it just for sticking in temporarily for a quick dump?

If the former, then I think it needs the early-return at the least (and probably _should_ have the key parameter).

But I get the feeling that you really just want the latter, and are only grudgingly being pushed into the former by Junio's suggestion.
