... if the `impl Trait` is represented as an `AliasTy` itself, instead of a placeholder. I couldn't actually write a test for this that fails here, because chalk-integration represents opaque types as placeholders (i.e. application types with `TypeName::OpaqueTy`) immediately, instead of using `AliasTy`. I'm not sure that's correct?
