/**
 * @assertion . . . if q is a generative constructor, then:
 * A fresh instance i, of class R is allocated. For each instance variable
 * f of i, if the variable declaration of f has an initializer expression ef,
 * then ef is evaluated, with the type parameters (if any) of R bound to the
 * actual type arguments V1, ..., Vl, to an object of and f is bound to of.
 * Otherwise f is bound to null.
 * Observe that this is not in scope in ef. Hence, the initialization cannot
 * depend on other properties of the object being instantiated.
 * @description Checks that a fresh instance is allocated with every
 * constructor invocation even if the class has only constant constructors,
 * one of which is being invoked by the new expression.
