Yurii, I agree with Raymond that it's probably not worth adding new ABCs for this. I'm happy to consider patches that add these operators to concrete stdlib mappings on a case-by-case basis. However, please be aware that we already went through a fairly comprehensive review of each dict/Mapping/MutableMapping subclass (real or virtual) in the entire stdlib to see if they would benefit here. I don't think we bothered updating *any* classes that weren't publicly documented, which is probably why "SignalDict" was left untouched. It's also important to remember that the motivating use-case for PEP 584 was binary "|", and that "|=" just logically followed from that change. In this specific case, I think just using the good ol' update method (or even item assignment) is probably good enough. I'm not very familiar with how SignalDict is used, though: do we ever actually want to create a new updated copy using binary "|"? That would probably be enough to convince me. ---------- components: +Library (Lib) -Regular Expressions versions: +Python 3.10 -Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43085> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
