/// @assertion A mixin declaration defines an interface. The interface for this
/// mixin declaration is equivalent to the interface of the class declared as:
///  abstract class A<X extends S, Y extends T> extends A$super<X, Y>
///    implements D, E { body' }
/// where body' contains abstract declarations corresponding to the instance
/// members of body of the mixin A.
/// It is a compile time error for the mixin declaration if this class
/// declarations would not be valid.
///
/// @description Checks that it is a compile-time error for the mixin declaration
/// if its super classes contain getters with the same name and different return
/// types.
