I am not happy about exposing every internal types. I prefer duck typing. Like OrderedDict, not all dict subtypes uses `dict_keys`, `dict_views`, and `dict_items`. If typeshed annotate dict.keys() returns `dict_keys`, "incompatible override" cano not be avoided. I prefer: * Keep status-quo: keys().mapping cause false positive and user need to suppress. This is not a big problem because `.mapping` is very rarely used. * Or add `.mapping` to `KeysView`, `ValuesView`, and `ItemsView`. Force every dict subclasses to implement it. ---------- nosy: +methane _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46399> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
