There was a problem hiding this comment.
I'm going back and forth whether we should use replace_escaping_bound_vars_uncached here instead...
If you don't want to use that, can you at least leave a FIXME saying that this only needs to deal w escaping bound vars (and not, e.g., early-bound regions), and it currently doesn't handle ty/const late-bound vars correctly?

…-in-self-ty, r=compiler-errors Use region-erased self type during IAT selection Split off from rust-lang#109410 as discussed. Fixes rust-lang#109299. Re UI test: I use a reproducer of rust-lang#109299 that contains a name resolution error instead of reproducer [`regionck-2.rs`](https://github.com/rust-lang/rust/blob/fc7ed4af165c27ab5914b93251194f826920cc65/tests/ui/associated-inherent-types/regionck-2.rs) (as found in the `AliasKind::Inherent` PR) since it would (incorrectly) pass typeck in this PR due to the lack of regionck and I'd rather not make *that* a regression test (with or without `known-bug`). `@rustbot` label F-inherent_associated_types r? `@compiler-errors`
