* @assertion A generic class declaration introduces a generic class into the
* enclosing library scope. A generic class is a mapping that accepts a list of
* actual type arguments and maps them to a class. Consider a generic class
* declaration [G] named [C] with formal type parameter declarations [X1 extends
* B1,..., Xm extends Bm], and a parameterized type [T] of the form
* [C<T1,..., Tl>].
* Otherwise, said parameterized type [C<T1,..., Tm>] denotes an application of
* the generic class declared by [G] to the type arguments [T1],...,[Tm]. This
* yields a class [C0] whose members are equivalent to those of a class
* declaration which is obtained from the declaration [G] by replacing each
* occurrence of [Xj] by [Tj].
* @description Checks that each occurrence of [Xj] is replaced by [Tj] for
* generic class [C0].
