I misinterpreted you then, sorry. I guess also because Elliot shortly after retrated from the approach, saying he "rewrote unsafe_tuple_compare to move the less-than after the equality testing, to make sure it's 100% consistent". I'd say the inconsistency the program showed was different. Yes, the xs got sorted differently than the ys, but the xs differed from the ys. The proposed method would change comparisons of *the same* tuples. You'd for example no longer have "sorted(tuples) == [min(tuples), max(tuples)]" for a list of two tuples. Also curious factoid: I recently saw a case where despite the "only <" promise, sorting caused an "x > y" comparison (because "y < x" wasn't implemented). (tiny note: tupsort.py does "range(2", should be "range(1" I think) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45530> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
