var Animal = _.inherit({
  name: 'Chupacabra',
  sound: 'roarmeowbarkmoo',
  sing: function () {
    alert(this.name + ' says ' + Array(5).join(this.sound));
  }
});

var HardWorker = _.inherit();

var Dog = _.inherit(Animal, HardWorker, {
  name: 'Gunner',
  sound: 'woof'
}, {staticProp: 'hello'});

var Cat = _.inherit(Animal, {
  name: 'Mittens',
  sound: 'meow'
});

(new Animal()).sing();
(new Cat()).sing();
(new Dog()).sing();

// (new Cat) instanceof Animal === true
