Oops, sorry - while implementing another PR, I realised this is probably going to conflict with something else we'll need to do in |
Sorry, something went wrong.

Thanks for the quick review anyway Jelle :) I'll integrate those suggestions in the upcoming PR. |

We agreed in #91162 that unpacked type arguments should only be valid to generic aliases that can accept a variable number of arguments - that is, unpacked type arguments should only be valid to generic aliases with a TypeVarTuple in the type parameters.
@JelleZijlstra Could I ask you for review on this?
(This PR is based on #92249, so there are a couple of extra commits. See the latest commit for the one that's actually part of this PR. I think I should be able to effectively hide the changes from the extra commits once #92249 is merged - so we can start review on this PR now?)
