Yeah, I've only recently started looking into this as well and I'm still unsure.

Yeah... I've never seen that done before and hope I never see it in actual code.

I'm not so sure it's about making js more powerful,
from what I've seen so far it just looks like a way to abstract away the
details of web development allowing the use of the latest GUI coding patterns.
To my mind, whereas this certainly makes developing web content easier for all
those java and similar object oriented programmers out there,
it doesn't really increase the power of js.

I've not looked through jquery to see if it does this,
but I seem to remember seeing the below code a bunch of times in js functions on
websites which don't work with edbrowse:
var document = some.set.of.js.calls();

I can't remember what went after the = but I remember wondering why anyone
would want to define the document variable and being somewhat surprised to see
that people actually did this.

I think if we can get child nodes working though that'd certainly help.

Sorry I don't have more time to look into this at the moment.

Cheers,
Adam.
