I think you are underestimating how badly Python dicts depend on decent hash functions. See: http://trac.sagemath.org/ticket/19331#comment:4 A change like this runs a real risk of degrading performance on certain code (that people might be relying on!) that currently runs correctly to such a level that it is effectively broken. That's not the kind of change one should make in a release candidate. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
