Allow a mobile-friendly framework (Zepto) to be used in place of jQuery about backbone

What's the deal with unbinding callbacks in Zepto? Can you never remove a callback?

[thejefflarson]

I've been using a combination overriding delegateEvents on a child class and and a similar patch to zepto that calls removeEventListener with the callbacks in the events object. It's a pain because there's no remove all events call like in jQuery. Anyhow I just opened a ticket over there:

Correct me if I'm wrong, but looking at the Zepto source:

https://github.com/madrobby/zepto/blob/master/src/zepto.js

It seems like there are 3 places where addEventListener is mentioned, and no places where removeEventListener is mentioned. Kinda seems like Zepto is still half-baked at this point, if there's no way to unbind the events you've added...

[thejefflarson]

Exactly, I think it's an oversight on zeptos part and not something backbone should worry about.

Let's freeze this one until Zepto gets a little more baked than it is currently -- Jeff's ticket still hasn't been addressed.

Is there anything else needed/desired from zepto? This would be useful to me and I'll invest the time to write the needed functionality for zepto.

I've got all the Backbone tests passing with a modified fork of Zepto:

Alright, Zepto 0.2 is out, as is Backbone 0.3.3, with Zepto support. Thanks for taking care of all the hard work, Sam. Closing the ticket.
