This happens when you use a mutable default value like a list or dictionary
instance, and you write to that default value. Python only keeps a since
instance of that default for the entire function definition. It is just a
common python gotcha to keep in mind. You wouldn't see this problem if you
only ever read from the variable and not add to it.
