I'm in favor of giving warnings about any one of these (we shouldn't
actually change any behavior right now, of course).
I agree with Alan that the current behavior (allowing multiple args
where the last one might be assumed to be nil) is bad (regardless of
how consistent it is), and I think both options are a fine way to warn
users.
