Returning the same object is just a micro-optimization and we've decided that it isn't worth it. In bpo-40521, frozenset() stop being a singleton. This costs a small bit of space but saves code complexity and a bit of execution time (especially given that we no longer have cheap access to global state). Thanks for the suggestion, but we'll pass. ---------- nosy: +rhettinger resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44703> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
