I'm assuming list.pop() is O(1), i.e. constant time.  Is it not?

Of course, one of my pet peeves about Python is that the complexity of 
the various container operations are not documented.  This leaves users 
needing to guess what they are, based on assumptions of how the 
containers are probably implemented.
