Why is there an AwaitableGenerator in the test data typing stub when there isn't one in the real typing module?

Because this stub (despite its extension) is actually a stub. It matches the real typing.pyi, not any real typing.py.

Oh okay. That makes sense.

Wouldn't it be simpler to just look at the fullname instead, like we do elsewhere?

Both crawl.py and crawl2.py pass cleanly now!

I think the bit of motivation is worthwhile here too.

Mostly streamlined the comments, but also decided that return in a generator not explicitly declared as returning Any or Generator should be None.
NOTE: the Matrix test is currently failing.
Upgrade AwaitableGenerator to four parameters -- the last one preserves the original type, which we sometimes need.
