Me too. It also seems option 2 doesn't help us decide what it should
do: I still think that raising StopIteration(value) would be
misleading to vanilla users of the generators.
Agreed. (I still think new syntax is a plus, though, as it helps to
clearly signal both the intent to make the generator a "subtask" and
the need to call it with yield-from. Readability counts.)
