// Regression test for <https://github.com/rust-lang/trait-system-refactor-initiative/issues/171>.
// Tests that we don't try to replace `<V as Super>::Output` when replacing projections in the
// required bounds for `dyn Trait`, b/c `V` is not relevant to the dyn type, which we were
// previously encountering b/c we were walking into the existential projection bounds of the dyn
// type itself.
