mv_embed has some functions for doing exactly that.
You can run something like: doLoad({list, of, classes, that, i need}, function(){ //code to run now that all those components have been included. }
It plays well with the script loader and loads it all the requested components in a single scriptLoader request. If you have already loaded some of those libraries it skips the classes it already has available.
and is a bit simpler than the YUI framework I think ;)

Speaking of libraries and all, I think it's worth merging libraries in general and figuring out a way for skin and extension developers to include libraries in the way that system can only:
- include a library once
- include latest library unless absolutely necessary
- maybe even load parts of the library on demand (
http://developer.yahoo.com/yui/yuiloader/ is an example of what I'm talking about).
Maybe it's also worth adding some JS bundles functionality where main bundle is global JS to be loaded on all page and there can be more bundles to load the rest of the code on pages that need them. My point is that this decision could be made in MW and not in the extensions - system should know what is bundled where and ignore inclusion request on the page if, let's say, YUI is already loaded in main bundle.

That's great news. I've been programming in JavaScript quite a lot the last few years and i think i would've probably gone insane if i hadn't discovered jQuery. Especially for complex and intricate HTML selections it's pretty amazing what you can do with jQuery.
Also, the fact that animations are built into the core could mean it might get a little bit more simple to do visually cool things, which might make the UI more intuitive.

Guys,
It's great to see that you're working in this direction - I'm thinking
about
working on this for a while, but didn't have a gut to undertake such ambitious project alone ;)
Do you have a working instance of ScriptLoader anywhere so I can aim some performance tools at it?
Thank you,

These changes will probably result in some minor adjustments to existing skins. (I will try not to completely break compatibility cuz I know there are many custom skins out in the wild that would be no fun to stop working once they update medaiWiki)
This consolidation of <head> includes _may_ result in _some_ un-updated skins referencing the same files twice which I think most browsers genneraly handle "oky"
Enabling $wgEnableScriptLoader will not work so well with skins that have not been updated. Should have a patch soon. more about
scriptLoader:
http://www.mediawiki.org/wiki/ScriptLoader (We will most likely ship with $wgEnableScriptLoader off by default )
I am also very excited about jQuery making its way into core. Things like the add_media_wizard are much easier to put together with jQuery's nifty abstractions and msg system. More about add media wizard:

Just a heads-up --
Michael Dale is working on some cleanup of how the various JavaScript bits are loaded by the skins to centralize some of the currently horridly spread-out code and make it easier to integrate in a centralized loader so we can serve more JS together in a single compressed request.
Unless there's a strong objection I'd be very happy for this to also include loading up the jQuery core library as a standard component.
The minified jQuery core is 19k gzipped, and can simplify other JS
code
significantly so we can likely chop down wikibits.js, mwsuggest.js,
and
the site-customized Monobook.js files by a large margin for a net
savings.
If you've done browser-side JavaScript development without jQuery and wanted to kill yourself, I highly recommend you try jQuery -- it's sooooo nice. :)
