First try on: http://trac.sagemath.org/sage_trac/ticket/13949
at least tests in sage/matrix pass ... This project nearly seemed painful due to the required changes to pickling, but then it turned out that pickling isn't implemented for matrices anyway, so no outdated pickles should exist. I haven't changed 2x2 there yet. I noticed that Matrix._cache also needs initializing, to an empty dict. Is that too expensive as well? (I guess 2x2 shortcircuits its init as well). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
