Of course not.  But that's not the corresponding
error message, is it?

Now that you bring that up, I don't see any good
description of the error message itself, either.
So yes, that's perhaps the first thing to fix.

Ideally the message should be self-explanatory,
and should indicate what the range is that the
specified args fall outside of.
