PS, getting more off-topic, I'm somewhat surprised that the above is more
compact and readable than the obvious generator-less equivalent:
class Outer:
[snip snip]
def __iter__(self):
return self
def next(self):
if self.isAtEnd():
raise StopIteration
else:
result = self.outer.currentState()
self.outer.advanceState()
return result
