Ah yes; thanks.

So Common Lisp is unequivocally in the camp of
requiring at least two args.

And if Elisp follows that (which I think it should,
unless someone can present a good use case for just
(apply FUNCTION)), then it should raise an error if
there are not at least two args.

Just one opinion.
