I have just pushed a commit to a topic branch in my repo[0] that fixes the warnings about __eq__ overriding __hash__ when sympy's tests are run with the -3 flag. Included below is the full commit message. Comments?
[0]: http://github.com/xiongchiamiov/sympy/tree/2to3-support --------------------------------------------- Define __hash__ functions when __eq__ is overriden for Py3k support. As hinted at in a bugreport[0] and implemented several years ago in the py3k branch[1], in Python 3, overriding __eq__ without explicitly defining __hash__ will cause __hash__ to be set to None. I have merely defined __hash__ functions so that python2.7 rc2 will not display any warnings (about this) when run with the -3 flag. Since we had not defined __hash__ methods previously, they are just calls to the super-class's __hash__.
