@charris I'd say that this might be worth backporting to 1.26 (marked as such as of now(, though could you let me handle the backport? The rebasing will require a bit of work as a number of 2.0-only changes will have to be reverted. |

Closes #21505
Python 3.11 will add the new
typing.assert_typefunction, which is used for validating that two types are equivalent while static type checking. Switching from the type-comments, currently used for validating the revealed type, totyping.assert_typehas a number advantages:typing.assert_typeis agnostic w.r.t. the particular type checkers, so this means we could in principle easily run the tests with other type checkers besides mypy with fairly minimal changes to the relevant test functions.Probably want to merge after #24634 and #24587 to minimize merge conflicts.
