Anyone here who worked with coroutines, please share your opinions.
If familiar with RxJava2, please contrast both of them as well

Creating custom operator is waaaaay easier with coroutines. So creating e.g. rx-like operator is a breeze

[rafal]

fun <T, R> ReceiveChannel<T>.flatMap(context: CoroutineContext = Unconfined, onError: (Throwable) -> Unit = logOnError, mapper: suspend (T) -> ReceiveChannel<R>): ReceiveChannel<R> = produce<R>(context) {
    try {
        for (elem in this@flatMap)
            for (mapped in mapper(elem))
                send(mapped)
    } catch (t: Throwable) {
        onError(t)
    }
}

that's all it took for me to create flatMap "operator"
