There was a problem hiding this comment.
The diagnostic looks a bit silly. I don't know why we are choosing a 'b for the inner param.

Do not overwrite lifetime binders for another HirId. This PR makes higher-ranked bounds in where clauses a bit more principled. We used to conflate `for<'a> T: Trait` with `(for<'a> T): Trait`. This PR separates both binders. This caused issued with fn types, which have their own binder, causing us to overwrite the predicates's binders with `fn`'s binders, ICEing. Fixes rust-lang#98594
