I think I started reading the discussions after that had already been removed, so I don't know exactly what it was. But I doubt that it was *exactly* the above, because PEP 550 uses set and get operations instead of "assignment contexts" like PEP 555 (this one) does. We didn't forget it, we just don't think it's very useful.I'm not sure I agree on the usefulness. Certainly a lot of the complexity of PEP 550 exists just to cater to Nathaniel's desire to influence what a generator sees via the context of the send()/next() call. I'm still not sure that's worth it. In 550 v1 there's no need for chained lookups.
