This pattern/idiom is well-established:
struct A { virtual A* clone () = 0; };
struct B : public A { virtual B* clone (); };
But the above does not work when the pointers A* and B* are replaced by shared_ptr<A> and shared_ptr<B>:
struct A { virtual shared_ptr<A> clone () = 0; };
struct B : public A { virtual shared_ptr<B> clone (); };
Is there a workaround? Another way to solve the same problem? Thanks!
