| // Test that we are special casing "outlives" for opaque types. |
| // |
| // The return type of a closure is not required to outlive the closure. As such |
| // the following code would not compile if we used a standard outlives check |
| // when checking the return type, because the return type of the closure would |
| // be `&ReEmpty i32`, and we don't allow `ReEmpty` to occur in the concrete |
| // type used for an opaque type. |
| // |
| // However, opaque types are special cased to include check all regions in the |
| // concrete type against the bound, which forces the return type to be |
| // `&'static i32` here. |
| |
| // build-pass (FIXME(62277): could be check-pass?) |
