Oh. You wanted a dictionary of sets ? Well, the main reason I have not rewritten this backend 10 times since I started working on Sage is that in order to replace it you need to deal with a wealth of unpleasant things : loops, multiple edges and labels. These things are a nightmare. This being said, I think that the memory cost of dict or dict and sets are comparable...
