/**
 * @assertion Execution of a generative constructor k is always done with respect to a set of
 * bindings for its formal parameters and with this bound to a fresh instance i and the type
 * parameters of the immediately enclosing class bound to a set of actual type arguments V1, ... , Vm.
 * If k is redirecting, , then its redirect clause has the form
 * this.g(a1, ..., an, xn+1: an+1, ..., xn+k: an+k) where g identifies another generative constructor.
 * Then execution of k proceeds by evaluating the argument list (a1, ..., an, xn+1: an+1, ..., xn+k: an+k),
 * and then executing g with respect to the bindings resulting from the evaluation of
 * (a1, ..., an, xn+1: an+1, ..., xn+k: an+k) and with this bound to i and the type parameters
 * of the immediately enclosing class bound to V1, ... , Vm.
 * Otherwise, execution  proceeds as follows:
 * Any initializing formals declared in k's parameter list are executed in the order they appear in the program.
 * Then, k's initializers are executed in the order they appear in the program.
 * After all the initializers have completed, the body of k is executed in a scope where this is bound to i.
 * Execution of the body begins with execution of the body of the superconstructor with this bound to i,
 * the type parameters of the immediately enclosing class bound to a set of actual type arguments V1, ... , Vm
 * and the formal parameter bindings determined by the argument list of the superinitializer of k.
 * @description Checks that type parameters are bound before execution of the constructor body.
