Extending the object model to support ecmascript v262 (es5) features

Reported by bjc | August 7th, 2010 @ 09:41 PM

Feature Request:

It would be nice to have the object model api to support es5 object and property features such as object freezing and read-only properties.

//-- start of bad use cases --

// example problem - read only properties (not sure of good api to help with this) MyEvent = Class.create({

initialize: function(data) {
    var d = data || {};

    // this needs to be improved (api wise)
    Object.defineProperty(this, "data", {
        value: d,
        writeable: false,
        configurable: false,
        enumerable: false,
    }
},

});

// example problem "final" classes. (demonstrated using proposed api) var KeyboardEvent = Class.extend(MyEvent, {

initialize: function(keycode, data) {
    $super(data),
    this.keycode = keycode;
},

freeze: true // or sealed etc.

});

//-- end of bad use cases

Please excuse the vagueness of this report. If there is any confusion don't hesitate to email me and i'll try and describe the request further.
