// Test for issue #57362, ensuring that the self ty is shown in cases of higher-ranked lifetimes
// conflicts: the `expected` and `found` trait refs would otherwise be printed the same, leading
// to confusing notes such as:
// = note: expected type `Trait`
// found type `Trait`
// extracted from a similar issue: #57642
