My question above is misleading with respect to my personal feelings
about the issue. It should have been:

"""*If* we decide we need to be able to assign to names in outer scopes,
would it be a good idea to add a rebinding operator?"""

I actually don't care much whether the cability is added or not, but
*if* we add it, I'd much rather see a rebinding operator than an
extension to the global statement or a new declarative statement.
