Clarification: you don't _have_ to do this to be compatible with 2.4. The sets module is in both 2.3 
and 2.4. The difference in 2.4 is that set is also a built-in data type implemented in C with the 
same interface as sets.Set. The code above will take advantage of the built-in set if it is 
available, otherwise use sets.Set.
