That's why I said I wanted a better iter, not some equality-overriding
object strawman thing.

I was thinking more like this:

    for profile_id in iter(None)(client.spop, "profile_ids"):

or alternatively:

    for profile_id in iter(bool)(client.spop, "profile_ids"):

Or perhaps either as keyword arguments (which is the only reason I
curried iter).

The interesting case for in-place assignment is not here. This is a
trivial case. It's in cases like this:

    while True:
        x = foo(bar())
        if x is None: break
        if x % 2 == 0: break

        print x

Imagine doing that with iter. :)
