This is bad news for me.
Maybe you can help me though. My users can create some classes in a
particular order which are stored at runtime in an array. But I want
to make this persistent, i.e. storing in a cookie. I thought about
building a serialized string which contains the class/constructor and
the constructor arguments for each object. I've helped myself with the
following hack:

Car=Class.create({
  initialize: function() {
    this._class="Car";
  }
});

var benz=new Car();

//recreated benz
var benzclone=eval("new "+benz._class+"()")

Pretty dirty, isn't it. Or does someone know a better method?
