/// @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 invocation
/// of a redirecting constructor.
