/// @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. Test several interfaces in 'on' and 'implements' clauses
