The only sane proposal i've seen that consistently addresses all
these cases, doesn't create new ambiguous situations, and doesn't
break most existing Python code is the "nonlocal" declaration.
nonlocal x
means
"Don't make a new binding for x in the local scope."
With this declaration, any binding statements modify the x that
is visible from an outer scope instead of creating a local x.
