I'd rather see a simpler rule: = never defines a variable in a surrounding
scope. If you want to affect the binding of such a variable, you have to
define it explicitly in the scope in which you want it.
Example:
x = 42
def f():
x = 123 # rebinds x as defined above
y = 123 # defines local variable
f()
print x # prints 123
print y # error -- y not defined
Yes, I know that rule is too simplistic. But I think I'd still prefer it to
the way things are now.
