John,
While I'm glad to see a scope arg available, i still think this is negligent
to the future of jQuery and ES standards. I really think a fn.bind()
implementation would ideal (since it would be jQuery-wide and not just
available in one function), but as I've noted in the past and is exampled
here, beginners may find this syntax a bit boggling:
$(foo).bind('event', fn.bind(bar) );
