Virtual functions and inheritance

[Baz via Digitalmars-d-learn]

even more weird:

---
module test;
import std.conv;

interface Meh{
     final string typeName()
     {return to!string(this);}
}

class Parent : Meh {}

class Child : Parent {}

void main() {
   auto p = new Parent;
   auto c = new Child;
   assert(p.typeName == __MODULE__ ~ ".Parent");
   assert(c.typeName == __MODULE__ ~ ".Child");
}
