| * 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 there is no compile time error if [T] is well |
| * bounded. |
