In any case, that's my personal opinion of course. What we should do is decide collectively if immutability is defined behaviour. If we decide that it is, we need regression tests. If we define that as "nice to have" but ultimately "implementation-defined" we don't. In any case, I would argue that having tests is good and allow us to know when the behaviour flips without people intending it to, like what happened in this case. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43908> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
