I'm learning RxJava 2.0 (with Kotlin bindings); can anyone give me a hint as to why <Observable>.subscribe(Observer<? super T> observer) doesn't return a disposable..?
I can't see how I can unsubscribe anything subscribed in this way, lack of a mechanism like this looks like too big a flaw to be correct...
