   5 // Regression test for #37291. The problem was that the starting
   6 // environment for a specialization check was not including the
   7 // where-clauses from the impl when attempting to normalize the impl's
   8 // trait-ref, so things like `<C as Foo>::Item` could not resolve,
   9 // since the `C: Foo` trait bound was not included in the environment.
