How to create class using object literal notation in javascript?

I want to create a class in Java Script. I can use basic functions coupled with prototypes but I want to use Object Literal Notation. Is is possible to create classes using Object Literal Notations?

Cannot be done....well, depends on how you define the params of the requirements. Should be done? Up for debate.

The following is from an idea a coworker of mine had.

http://bit.ly/18xGdKi [JSBin with console example]

if (typeof (makeClass) === "undefined") {
  makeClass = function(o) {
    var F = function () {};

    if (typeof (o) === "object" && o !== null) {
      if (typeof (o.constructor) === "function") {
        F = o.constructor;
      }

      F.prototype = o;
    }

    return F;
  };
}

var MyClass = makeClass({
  constructor: function (pName) {
    var _myPrivateIdaho = 'Idaho ' + pName;
    this.name = pName;

    var _myPrivateFunc = function() {
      console.log('You are in my ' + 
                  _myPrivateIdaho +'.');
    };

    _myPrivateFunc();
  },
  getName: function() {
    return this.name;
  }
});

new MyClass('Bob');
new MyClass('Steve');

You cannot create an instance of an object (and yes, you could even see functions as objects in Javascript, but I'm talking about literal defined objects), you must use a function to define a reusable class.
