Heya John,
Thanks for the response, and sorry I wasn't more clear. I've tried so
many different variations of this, that I can't remember which did what.
That one does keep the chain properly in place, but this doesn't work:
subClass('body') // Should error out and say subClass.fn.init is not a
constructor.
Every way I was able to get the above to work, it would only do so by
maintaining the link between subClass.fn and jQuery.fn.
Is there any other way you can think of that would essentially (and in
a way that's performant) extend a new object off the jQuery object?
Thanks again for your guys time :)
