/// Types of members from super-bounded class types are computed using the same
/// rules as types of members from other types. Types of function applications
/// involving super-bounded types are computed using the same rules as types of
/// function applications involving other types. Here is an example:
///   class A<X extends num> {
///     X x;
///    }
///    A<Object> a;
///    With this, [a.x] has static type Object, even though the upper bound on
///    the type variable X is num.
