According to the docs (https://docs.python.org/2/library/2to3.html) it should have renamed long to int. I also tried something closer to Chris's suggestion, try: long except NameError: long = int class C_hash(long): # etc. but (tentatively) opted for something that avoided creating new names at the module level. If it doesn't look too terrible I might stick with it for now (although I am quite tempted to go back to the above). Thanks Skip and Chris.
