Thoughts?

I tried to define the error messages in terms of the callee's signature. I call the formals that are not variadic, keyword variadic, or keyword-only, positional. For example, in

def f(a, b, c, *args, d): pass

a, b, and c are positional. Hence the "positional" in error messages.

But since the error message gives the name of the parameter, there doesn't seem to be a point to add that it's "positional": it can be trivially deduced from the function signature.
