`Object.clone` returns a raw object with a shallow copy of the
properties of the object you give it. It is not a perfect copy of the
object down to the prototype level:
var a, b;
a = [1, 2, 3];
b = Object.clone(a);
dis
I try
var o = {};
o.name = 'propertyName';
alert(o.keys); --> undefined
why? but in debugger I see that Object has all methods, but o - not!

it's general example for show the problem with Object.clone :)
Usually I use anothe technique:
var a = Class.create((function(){.
var instancePrivates = [];
function initialize(){
var internalId;
instancePrivates.push({});
internalId = --instancePrivates;
in last example of course
this.internalId = --instancePrivates;
instead of
var internalId;
internalId = --instancePrivates;

that sample was to demonstarte Object.clone bug :)
Usually I us to
var a = Class.create((function() {
var _privates = [];
function initialize() {
_privates.push({});
this.internalId = _privates.length-1;
_privates[this.internalId].items = []; <-- here the instances i

It's not a bug, though I'd say detecting that it's being fed an array
wouldn't be a bad feature to add.

`keys` is not an instance method, it's a method of the `Object`
function:
alert(Object.keys(o)); // "name"

If you add something to `Object.prototype`, it shows up on *every*
object. So for instance:
Object.prototype.foo = function() {
return "bar";
};
var a = {};
console.log(typeof a.foo);
// -> "f
