/**
 * @assertion Evaluation of an assignment of the form e1.v = e2 proceeds as
 * follows:
 * The expression e1 is evaluated to an object o1. Then, the expression e2 is
 * evaluated to an object o2. Then, the setter v = is looked up in o1 with
 * respect to the current library. If o1 is an instance of Type but e1 is not a
 * constant type literal, then if v = is a setter that forwards to a static
 * setter, setter lookup fails. Otherwise, the body of v = is executed with its
 * formal parameter bound to o2 and this bound to o1.
 * @description Checks that an assignment of the form e1.v = e2 is evaluated
 * correctly if e1 is a constant type literal
