Ruby-style classes in ECMAScript 5

ruby-class.js

var Class = Object.create(null, {
  "new": {
    "value": function () {
      var result = Object.create(this, {
        "class": {
          "value": this
        }
      });
      result.initialize.apply(result, arguments);
      return result;
    }
  },
  "initialize": {
    "value": function () {},
    "enumerable": true,
    "configurable": true,
    "writable": true
  }
});

var Person = Class.new();
Person.initialize = function (name, age) {
  this.name = name;
  this.age = age;
}
Person.speak = function (message) {
  return this.name + ": " + message;
};

var kit = Person.new("Kit", 18);
kit.speak("Hiya!");

Person.class === Class;
kit.class === Person;
