While I agree that it was badly named, on thinking further about it, I'm
not sure that "nothing" (i.e. "no thing") is the right name. The right
name is "no thingS". So that would be

class noThings:
    def __init__(self):
        raise StopIteration()

def emptyGen:
    yield noThings()

hair-splitting-ly yrs :-)
