Could we revert abstract types in `typing` to respond True to `isinstance(..., type)` again? I don't want singledispatch, or any other library like it, to have to special-case typing. Especially for *non-generic* variants, responding True to `isinstance()` seems reasonable to me. We cannot dispatch by `Sequence[int]` and some such so it makes sense for *those* to keep failing going forward. The current suggested workaround of using abc.Sequence instead will work. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34498> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
