By the way, here's how to emulate the value-returning-close() on a
generator, assuming the generator uses raise StopIteration(x) to mean
except StopIteration, err:
I like this because it's fairly straightforward (except for the detail
of having to also catch GeneratorExit).
In fact it would be a really simple change to gen_close() in
genobject.c -- the only change needed there would be to return
err.args. I like small evolutionary improvements to APIs.
