[whatwg] Intergrating the DOM and JavaScript (JSDOM)

At the moment, DOM objects are specified in a language neutral way. 
That's fine. However, this makes these objects uninteresting and 
cumbersome to script with.

Mozilla has a more integrated programming environment. It exposes DOM 
objects as native JavaScript objects. That means I can do things this 
like this:

Object.prototype.foo = "bar";

==> "bar"

A trivial example but it demonstrates that the DOM and JavaScript are 
not totally separate on a Mozilla platform. This is very cool. 8-)

It would be great if NodeLists were subclasses of JavaScript Array 
objects (especially with the introduction of Mozilla's Array Extras 
[1]). This makes iteration over DOM queries more flexible.

I guess what I'm proposing is a new DOM API. One which is specified with 
JavaScript in mind. A redefinition of DOM objects as subclasses of 
JavaScript objects. Mozilla already does this by and large. It makes 
that browser a dream to program with.

Is this within the remit of the Web Apps spec? This seems like a 
fundamental change in terms of browser architecture so I would 
understand if it was too difficult to implement in the short term.

But it would be cool.
