The documentation situation was complained of in the 2009 thread I just
cited :-(. Doesn't look like anybody did anything about it.
I am not, however, persuaded that you can just move a bunch of that
material to the syntax chapter.
That wasn't the intent, but the exact solution will take time to come up with so I was just being vague.
I don't think it's very practical
to describe variadic functions when the user doesn't know how to
create one.
Plenty of users are able to execute built-in functions without knowing how to create them. This doesn't seem any different.
