Don't assume traits used as type are trait objs in 2021 edition Fixes #127548 When you use a trait as a type, the compiler automatically assumes you meant to use a trait object, which is not always the case. This PR fixes the bug where you don't need a trait object, so the error message was changed to: ``` error[E0782]: expected a type, found a trait ``` Also fixes some ICEs: Fixes https://github.com/rust-lang/rust/issues/120241 Fixes https://github.com/rust-lang/rust/issues/120482 Fixes https://github.com/rust-lang/rust/issues/125512 |
