Hard to make sure, so, it would always be "MIGHT be used before
assignment". E.g.,
def f():
for i in range(6):
if i>0: print x,
x = str(i)
this is OK... no UnboundNameError. Now, change the if's guard to
if SolveTuringHaltingProblem(i): print x,
to see why it's hard to make sure about this at compile time.
A warning might still be OK of course, even though it may need to
be worded in wishy-washy "might" terms -- this IS peculiar usage.
