Comment 3 for bug 1612066

In a loop body, conditionals below does not always run before conditionals above

for example: statement_2 does not necessarily run after statement_1

while condition_1:
    if condition_2:
        statement_1
    else:
        statement_2

@bitglue
I think treating all variables defined in other branches as defined can silence the warning.
I have no opinions on whether doing this can be justified by the reported case, though.

@asmeurer
I said false positive because Pyflakes warned of code that can be run in the python interpreter. Maybe I have used the term incorrectly.

Also, at least to me, the problem seems to be more clear now. I can update the original report if needed.
