[jQuery] jQuery namespacing your code

[jQuery] jQuery namespacing your code

Hi all.  With a lot of developers writing javascript these days, it's easy to write something that collides with someone else's code.  I like Dojo's and YUI's approach to namespaced code.  So, I decided to create a plugin for jQuery that allows you to create namespaced objects... it's actually a transposed version of YUI's namespace function:
jQuery.namespace = function(ns) {
    if (!ns || !ns.length) { return null }
    var levels = ns.split(".");
    if (eval('typeof '+levels[0]+'=="undefined"')) {
      eval(levels[0]+'={}');
    }
    var nsobj = eval(levels[0]);
    for (var i=1; i<levels.length; i++) {
        nsobj[levels[i]] = nsobj[levels[i]] || {};
        nsobj = nsobj[levels[i]];
    }
    return nsobj;
};
Feed it a namespace:
$.namespace("org.jquery.utils")
Then start using your new namespaced object:
org.jquery.utils.HelloWorld = function() {alert('hi')}
This would actually be a nice feature to add to the base jQuery library... any thoughts on that?
