def f(): def g(x): z := x ... That is, in the absence of a pre-existing binding, where does the binding for := go? I think it should be equivalent to global, going to the module scope.
I think it should raise some subclass of NameError, because it's not an assignment to an _already-existing_ nonlocal, as per my text quoted above. It does not seem to me that "nested functions able to rebind module-level names" has compelling use cases, so I would prefer the simplicity of forbidding this usage. Alex
