The important point is in 20.f: "The overriding declaration for P2.Op_B is not visible in Main, so the name in the call actually denotes the implicit declaration of Op_B inherited from T1." Note that there is an implicit declaration of Op_B in P2 at the point of the type extension. Also note that X is not declared in P2; it is declared in Main. -- Jeff Carter "My brain hurts!"
