Small JavaScript library for better OOP syntax

This is small JavaScript lib that provides simple syntax for Classes & Packages in JavaScript language. Current implementation is for MooTools OOP, but it can be very easilly modified to support any other OOP library (see _ClassDecl definition)

Example

namespace('my.namespace', function() {
    function myPrivateOutputFunction(text) {
        console.log(text);
    }

    var myPrivateVariable = 'Hello ';

    fun('test', function(name) {
        myPrivateOutputFunction(myPrivateVariable + name);
        })
    };
});
namespace('my', function() {
    namespace('namespace', function() {
        clazz('MyInternalClazz', function() {
            fun('test', function() {
                my.namespace.test('new syntax for OOP!');
            });
        });
    });
});

var instance = new my.namespace.MyInternalClazz;
instance.test();
