My limited low-level Python knowledge leads me to believe that this could also be done using __new__ but I also read that most magic methods get called as type(Foo).__magic__(bar, ...) so that might not be possible. (However also no methods can be declared on a TypedDict class so that might not be a problem?) > Maybe it's written up in PEP 589, but I suspect not (I skimmed and couldn't > find it).

I asked [here on typing-sig](https://mail.python.org/archives/list/typing-...@python.org/thread/RNFWPRLHTUTZES2FDSSMY472JFGMD4EW/) but did not yet get any responses. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41249> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
