[issue35069] Unexecuted import in function causes UnboundLocalError

[Steven D'Aprano]

Yes, that's exactly right. That's how local variables work in Python:

x = 999  # global x
def demo():
   if False:
       x = 1
   x  # local x has no value

does the same thing. This is standard, documented behaviour, regardless 
of which kind of assignment statement you use.
