bug#40968: 28.0.50; (apply nil)

[Drew Adams]

Dunno whether this has been mentioned in this
thread (haven't followed it).

The signature in Common Lisp (which is more or
less the _common_ ground of several Lisps from
the 70s & 80s) is this:

 (apply function arg &rest more-args)

I don't see why Emacs Lisp should be different.
Is there a good reason?  Is there some advantage
to being able to do just (apply #'foo)?  Why do
we use this signature:

 (apply FUNCTION &rest ARGUMENTS)
