Was hoping to have drop-in optional caching, e.g.

xhr = if settings.cache then $.retrieveJSON(url) else $.getJSON(url)
xhr.done(settings.done).fail(settings.fail).always(settings.always)

But when the $.retrieveJSON path is hit I just get Uncaught TypeError: Cannot read property 'jquery' of undefined.

Is this resolved by b2139ff?

Still doesn't look like the above example would work. That commit still requires a callback function. It also returns a promise that will never resolve, if you return false from your callback function if it is cached.
