 * @assertion A generic type alias is a declaration [D] of one of the following

 *    m typedef id<X1extendsB1, ..., Xs extendsBs> = T;
 * ...
 * where [m] is derived from metadata, [T] is a type, and [S?] is a type or the
 * empty string. Let [S0] be [S?] if it is a type, otherwise let [S0] be
 * [dynamic]. The associated type of [D], call it [F], is, respectively:
 *   T
 * ...
 * @description Checks that [T] should be a type.
