Sometimes you ask too many questions. :-)

Let's just say that this is a historically available name.  I don't
expect that isinstance(obj, generator) is a very common question to
ask, so I don't mind if you have to ask it in a somewhat awkward way.

Using new.py looks much better to me because it already works.
