| * @assertion A generic type alias is a declaration [D] of one of the following |
| * forms: |
| * m typedef id<X1 extends B1, . . . , Xs extends Bs> = T; |
| * ... |
| * 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. |
