/// @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 there is no compile time error if [typedef] has two
/// type parameters and one depends on the other.
