 *   ...
 * Under the assumption that X1, . . . , Xs are types such that Xj <: Bj, for
 * all j ∈ 1..s, it is a compile-time error if [T] is not regular-bounded, and
 * it is a compile-time error if any type occurring in [T] is not well-bounded.
 * @description Checks that it is not a compile time error in the difficult
 * ([X extends A<X>]) type parameter cases.
