For both generator, list and set comprehensions it makes sense, I think.
For dict comprehensions: not so much. That in itself is already sign
enough that probably the */** spelling would make more sense, while also
allowing the `yield *foo` alternative to `yield from foo`. But what
would be the meaning of `yield **foo`? Would that be `yield
*foo.items()`? I have no idea.
