// 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`

// from issue #57362
