@Jeff, I wrote test_diamond_inheritance, so I can address this question reasonably well. The MRO assertion is most likely wrong, given this change in C3 vs Java resolution. However, I believe the MRO computation should still be deterministic, based on the ordering of bases. Perhaps separate out in 2 assertions or even 2 tests? * Precedence of Iterable before Map * Determinism of MRO computation I would still recommend using stringification, then unpack for the actual precedence, eg mro_str[1:-1].split(", "), etc
