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.
