Thanks, @compiler-errors ! This looks great; I'm excited to try it. |

…bank Fix erased region escaping into wfcheck due to rust-lang#95395 We can just use `liberate_late_bound_regions` instead of `erase_late_bound_regions`... This gives us `ReEarlyBound` instead of `ReErased`, the former being something typeck actually knows how to deal with... Fixes rust-lang#96381 Side-note: We only actually get far enough in the compiler pipeline to cause this ICE when we're invoking rustdoc. We actually abort rustc right before wfcheck because of the error that we emit (having `_` in the type signature). Why does rustdoc keep going even though we raise an error?
