Thirded, for two reasons:
- A "yield x" expression has completely different semantics from
"yield from x"; that's a bad idea given how similar they look.
- Returning a value by stuffing it in the StopIteration abuses the
exception mechanism.

Without a compelling, concrete, example I'm -1 on the return part; +1
for the rest.
