/**
 * @assertion Evaluation of a conditional expression c of the form e1 ? e2 : e3
 * proceeds as follows:
 * First, e1 is evaluated to an object o1. In checked mode, it is a dynamic
 * type error if o1 is not of type bool. Otherwise, o1 is then subjected to boolean
 * conversion producing an object r. If r is true, then the value of c is the
 * result of evaluating the expression e2. Otherwise the value of c is the result of
 * evaluating the expression e3.
 * @description Checks that it is dynamic type error if e1 is not evaluated to a bool object.
