It does, but OTOH we're calling the lookup more than once, and that for me
justifies extra function (with a descriptive name), so that we don't have
to change multiple places in case the data structure changes in the
future.
But I don't have a strong preference either way, so I'll change it.

Fair enough; we'll be issuing the warning in cases where actual "harm"
would be caused, and that should be enough.
I'll trim down the CC list a little bit and submit v3 shortly.
