I just merged the revert. |
Source commit: python/typeshed@2370b8b
This is allegedly causing large performance problems, see 13821 typeshed/8231 had zero hits on mypy_primer, so it's not the worst thing to undo. Patching this in typeshed also feels weird, since there's a more general soundness issue. If a typevar has a bound or constraint, we might not want to solve it to a Literal. If we can confirm the performance regression or fix the unsoundness within mypy, I might pursue upstreaming this in typeshed. (Reminder: add this to the sync_typeshed script once merged)
… checking: python#13987 (comment) A manual cherry-pick of e437cdf.
