-/// Collects together a list of type bounds. These lists of bounds occur in many places
-/// in Rust's syntax:
-///
-/// ```text
-/// trait Foo: Bar + Baz { }
-///            ^^^^^^^^^ supertrait list bounding the `Self` type parameter
-///
-/// fn foo<T: Bar + Baz>() { }
-///           ^^^^^^^^^ bounding the type parameter `T`
-///
-/// impl dyn Bar + Baz
-///          ^^^^^^^^^ bounding the type-erased dynamic type
-/// ```
-///
-/// Our representation is a bit mixed here -- in some cases, we
-/// include the self type (e.g., `trait_bounds`) but in others we do not
