The trouble with taking that position is that the very
cases which would benefit are very *simple* ones, where
it would be cumbersome to refactor it to use a class,
or mutable object in the outer scope, etc. So you've
effectively set up your acceptance criteria to be
unmeetable.

There's one very simple way we could do this in Py3k
without requiring any new syntax or keywords: just
redefine the meaning of "global" to mean "not local".
