* @assertion The return type of a factory whose signature is of the

* parameters of the enclosing class.
* @description Checks that assigning the result of invoking a factory
* constructor to a variable whose type is not assignable to M<T1,...,Tn>
* produces a compile error. Factory constructor name is that of its
