Typing with Python is hard and constantly evolving. This is why we set up a forum to help users with typing at https://github.com/python/typing/discussions. It’s fairly new, but at the moment we have two categories for general Q&A and for asking for reviews. If you have questions about typing, please join us there or on our Gitter channel (python/typing - Gitter). If you maintain a typing-related package or typing-related documentation, we would be happy if you could add a link to the discussions forum to your documentation. Contributors to the forum and suggestions on how to improve it are most welcome.
The forum is intended as a help forum. Discussions about new features, improvements, and implementation should continue to go to the typing-sig list or to the appropriate issue trackers.
