Source commit: python/typeshed@fe2ebd6
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)
Since the plugin provides superior type checking: #13987 (comment) A manual cherry-pick of e437cdf.

Primer hits:
The test failure is caused by python/typeshed#10464. Should be fairly easy to resolve, I think (but I can't push to this branch). |
