* [3.12] Miscellaneous improvements to the typing docs (GH-105529) (#105567)Miss Islington (bot)2023-06-091-6/+6
| | | | | | | | Miscellaneous improvements to the typing docs (GH-105529) Mostly, these are changes so that we use shorter sentences and shorter paragraphs. In particular, I've tried to make the first sentence introducing each object in the typing API short and declarative.

* Improve assert_type phrasing (#104081)Shantanu2023-05-021-3/+4
| | | | | | | | | I'd like to make the fact that this does nothing at runtime really obvious, since I suspect this is unintuitive for users who are unfamiliar with static type checking. I thought of this because of https://discuss.python.org/t/add-arg-check-type-to-types/26384 wherein I'm skeptical that the user really did want `assert_type`.
