I meant this:

class foo {
  int value;

  this(int a) { value = a; }

  foo opAdd(foo other) { return new foo(value + other.value); }
}

class bar : foo {
  int value2;

  this(int a, int b) { super(a); value2 = b; }

  override foo opAdd(foo other) { return new bar(value + other.value, 
value2+1); }
}
