Still not enough pages about javascript objects and closures

Here's my clean and easy example.

var myObject = (function () {
  // private static, objectIdPool to keep an index
  // on all objects created
  var objectIdPool =0;
  return (function ( val ) {
			
    // private
    var myPrivate ;
    var myId;
			
    // privileged
    this.getPrivate = function () {
      alert ("object # " + myId + " private : " + myPrivate)
    };
    this.setPrivate = function ( val ) {
      myPrivate = val;
    };

    // execute at construction
    myId = objectIdPool++;
    myPrivate = val;
    alert (myId + ":" + myPrivate);
    });
} )(); // inline execution

var dummy0 = new myObject ("abc");
dummy0.getPrivate();  // returns abc from #0

var dummy1 = new myObject ("123");
dummy1.getPrivate();  // returns 123 for #1
dummy0.getPrivate();  // returns abc for #0

dummy1.setPrivate ("def");
dummy1.getPrivate(); // returns def for #1
dummy0.getPrivate(); // returns abc for #0

Another fine contribution to make google a better place.
