* @assertion The superclass of a class C that has a with clause with
* M1,...,Mk and an extends clause extends S is the application of mixin
* Mk*...*M1 to S. If no with clause is specified then the extends clause of a
* class C specifies its superclass.
* @description Checks that a class can indeed specify a superclass using the
* extends clause and an instance of this class is also an instance of that
* superclass. Test type aliases
