The inner scope can still be closed over via a lambda, such as in the
following. I think that makes changing the semantics of either a breaking
change.
>>> funcs = [lambda: i for i in range(2)]
>>> [f() for f in funcs()]
[1, 1] # often not intended, but demonstrates the last-value-assigned
semantics
