OK, so you've confirmed my doubt. I stand corrected.
(Actually, you've shown only that there exists an implementation (albeit a
common one) that prints a warning. That does not confirm that the CL spec says
that's OK. But I claimed IANAL...)
Perhaps this kind of message is a candidate for a :debug warning level? I
already said that it is useful for programmers. I do not see it as helpful for
general users just loading a library. On the contrary: some might become
confused, if not downright worried. That's all I'm trying to say.
