def func(x, y, *moreargs, foo, bar):
pass
Any positional args after x and y will go into moreargs, so foo and
bar have to be specified by keywords. (And are mandatory, since I
didn't default them.) If moreargs isn't given a name, then additional
positional args are forbidden, but the requirements on foo and bar are
the same.
