To me, the question suggests that closures inevitably go with nested scopes,
which is not necessarily so (UIAM ;-) I.e., ISTM that nested scopes
in general (as opposed to Python's) don't necessarily require closures, unless
you allow references to nested function definitions to escape their enclosing
scope, and be used elsewhere (as Python does allow). Cf. Pascal?
