Interestingly, I just saw a thread over at TurboGears(or is it this
group, I forgot) about this multiple return issue and there are people
who religiously believe that a function can have only one exit point.

def f():
  r = None
  for i in range(20):
  if i > 10:
    r = 10
    break
  if r is None: something
  else: return r
