Re: [fetch] Aborting a fetch (#27)

Imo promises is an abstraction to make async code look sync by providing it with return/throw/try/catch semantics. But if the abstraction doesn't fit the use case, than something else than promises should be used, like observables.
Ben Lesh gave a great talk about observables at ng-europe last month and why promises just don't work for ajax requests and why Angular 2 went with Observables for their http module https://www.youtube.com/watch?v=KOOT7BArVHQ
