That's not a generator expression, that's a generator function. Nobody
contests they can reference earlier states, that's most of their point :-)

For context, we're trying to build Turing Completeness into Python without

probably killed it :-) and this is entirely unrelated by now, except in
the vague sense he started with an (I'm sure entirely accidentally)
thought-provoking question.
