Considering adding a Cancelled event to RAC’s Swift API to reify disposal. It might simplify Signal lifetimes: github.com/ReactiveCocoa/
Conversation
Not sure what making it an event buys you: what general operation might you perform on a cancellation and also another?

It’s mainly for simplicity. Why shouldn’t consumers handle cancellation just like other forms of termination?

Hm. Seems to conflate with CompositeDisposable. Want to do more on cancellation? addDisposable! or… observe()… sometimes…

My goal would be:
- Producers add to Disposables
- Consumers handle Cancelled events
- Cancel by invoking dispose()

OK, think I follow. Unfortunately this may have to be one of those things where we can't evaluate until implemented…
FWIW, this also happens to clean up pipe() nicely.
