The change basically LGTM, but pytype is crashing. Also, pyright has quite different inference for generic parameters compared to mypy, so I think we'll struggle to find a test case test demonstrates the issue clearly while passing on both mypy and pyright. I'd be tempted to just skip the test case, personally. |

According to mypy_primer, this change has no effect on the checked open source code. 🤖🎉 |

Any ideas on what's wrong? |

looks like a pytype bug to me |

Oh, sorry! |

PR #13336 caused a regression in mypy, see python/mypy#18628
So, I changed
LiteraltoFinal, since it works and added a test case for the regression.
