The use case that prompted https://github.com/python/cpython/pull/31679 is that we are adding typings to `PyMongo`. We are late to using typings, because we only recently dropped Python 2.7 support. We have an existing options class that subclasses `NamedTuple`. We would like to make that class `Generic`, but are currently blocked. Our current workaround is to create a separate stub file that uses `class CodecOptions(Tuple, Generic[T])` and explicitly re-declares the `NamedTuple` API. Switching to `dataclass` would be disruptive, since we still support Python 3.6 and only rely on the standard library. We would also require a major version update since it would be an API change. ---------- nosy: +Steven Silvester _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43923> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
