Isn't this what NVI is all about?

import std.stdio;

interface Foo
{
    final void callable()
    {
        impl1();
        impl2();
    }

    void impl1();
    void impl2();
}

class Bar : Foo
{
    @disable void impl1() { writeln("impl1"); }
    @disable void impl2() { writeln("impl2"); }
}

void main()
{
    Foo foo = new Bar();
    foo.callable();
}

You can't directly call impl1() from within Bar, however you can call it via
the Foo interface. I think this is pretty much it, no?
