With C# semantics (as has been suggested as a basis):

class A {
    virtual void foo() {
        writeln("A.foo");
    }
}

class B : A {
     virtual void foo() {
         writeln("B.foo");
     }
}

void bar() {
     B b = new B();
     A a = b;
     a.foo(); // Prints "A.foo"
     b.foo(); // Prints "B.foo"
}
