Consider these two functions:
---
def nok():
    a = None
    def f():
        if a:
            a = 1
    f()

def ok():
    a = None
    def f():
        if a:
            b = 1
    f()
---

Function ok() executes fine, but function nok() trigger an exception:

Traceback (most recent call last):
  File "pb.py", line 20, in <module>
    nok()
  File "pb.py", line 7, in nok
    f()
  File "pb.py", line 5, in f
    if a:
UnboundLocalError: local variable 'a' referenced before assignment

There is no reason for this to happen
