Well, I guess I should have wrote the following instead:

---
class A {
    void foo( float a ) {}
    void foo( int a ) {}

    final void bar() {
      // Determine whether this.foo( 1 ) and this.foo( 1f ) really refer
      // to A.foo( float ) and A.foo( int ) or if they point to a subclass
      // implementation – how?
    }
}

class B : A {
    alias A.foo foo;
    override void foo( float a ) {}
}

class C : A {
    alias A.foo foo;
    override void foo( int a ) {}
}

class D : B {
    alias B.foo foo;
    override void foo( int a ) {}
}
