Not related to your change but the return of typing._SpecialForm just below should also return types.GenericAlias. The change itself looks right. |

Yeah, good point. I'll try changing that in a follow-up, since we'll probably want to backport this PR |

According to mypy_primer, this change doesn't affect type check results on a corpus of open source code. ✅ |
