At the risk of hypergeneralization... If *arg means "put the rest of the
positional arguments in arg", then if we simply allow arg to be a tuple...
def foo(*(a, b)): ... # disallow keyword args.
def foo(a, b, *(), x, y): ... # disallow positional args after b.
def foo(*(a, b), x, y): ... # a, b _must_ be positional; x, y keyword.
That () = () is currently a syntax error might be considered a reason to
use the lone star spelling instead of *(), but I find the tuple more obvious.
