Consider:class A { abstract void fun() {} } The class defines a function that is at the same time abstract (so it requires overriding in derivees) and has implementation. Currently the compiler disallows creation of objects of type A, although technically that is feasible given that A defines the abstract method. Should A be instantiable? What designs would that help or hinder? Andrei
If it were instantiable, what would be the difference between "abstract" and "virtual"?
