--- Comment #33 from Glenn Maynard <glenn@zewt.org> ---
Verifying the number of parameters is not "excess validation".  Verifying the
number of parameters is a useful and well-understood part of modern dynamic
languages.  See Python for a good example.

We can't get this everywhere in JavaScript due to heavy legacy constraints, but
that doesn't mean we shouldn't have it at all.
