Maybe, but it would break currently existing (and working) code like the
following...

#no foo = declaration

def init_foo():
    global foo
    foo = ...

I use variants of the above in a few places.  Could I initialize foo =
None in the module namespace prior to running init_foo()?  Sure, but
that may or may not clutter up definitions contained in the module.
