Oh, I think the call() thing is just me being confused. That's *only* a
mechanism to allow non-functions to look like functions? I guess my
misunderstanding is more about how apply is defined (it mentions call),
which really isn't important to me right now, so feel free to ignore that
part of my question. Sorry.
