This PR backports GH-31712 to 3.10. However, two key modifications have been made:
reveal_type(new in 3.11) have been removed.TypeVars to annotate alternative-constructor classmethods, has been added. This is one of the most important uses of boundTypeVars for Python versions <=3.10, but is no longer needed in 3.11 due to the addition oftyping.Self.https://bugs.python.org/issue46769
