As the patch works right now, any iterator will be exhausted,
but if the proposal is constrained to only allowing the *name at
the end, wouldn't a more useful behavior be to not exhaust the
iterator, making it similar to:
> it = iter(range(10))
> a = next(it)
> b = it
or would this be too surprising?
