My comments were assuming `f(**x for x in y)` meant `f({**x for x in y})`.
I see your reasoning, but I don't like how your version has
(x for y in z for x in y) == (*y for y in z)
f(x for y in z for x in y) != f(*y for y in z)
This seems like a tripping point. I've never wanted to unpack a 2D iterable
into an argument list, so personally I'm not convinced by the value-add either.
