Got it @raulraja. I actually finished my fake implement of ObservableZ<E, A> in my RxArrow when I was on the way home: https://github.com/lenguyenthanh/rxarrow/blob/master/src/main/kotlin/com/lenguyenthanh/rxarrow/ObservableZ.kt

Thanks, I use Observable<Either<A, B>> in my projects. Now it looks much better with ObservableZ<E,A> 😄
