Ha. Thanks :)

I actually think you need the little dance I've got there. When I change the code what you have, I get `Uncaught TypeError: Property '_super' of object [object Object] is not a function` 

I also tried `return request.always => @_super.call(@)` but that fails too with `Uncaught TypeError: Cannot call method 'call' of undefined `.

I believe both the receiver and the context need to be set in order to call `_super()` - which requires storing the method and then using `call`. Saying that, I'm extremely happy for you to show me a better way if you can find one :)
