Yeek, that makes it look like Logo!
What about simply
outer x = value
In this, 'outer' would be an annotation applicable to any
bare name in an lvalue position, so you could say
(x, outer y, self.z) = stuff
if you wanted, or even
def outer f():
...
class outer C:
...
although probably I wouldn't mind much if those were
disallowed.
