I think this code should be just equivalent to this code

    def g():
        temp = [(yield i) for i in range(10)]
        return (v for v in temp)

But then you get a non-lazy iterable, which defeats the
purpose of using a generator expression -- you might as
well have used a comprehension to begin with.
