fun <E> ReceiveChannel<E>.onEach(context: CoroutineContext = Unconfined, action: (E) -> Unit): ReceiveChannel<E> =
    produce(context) {
        consumeEach {
            action(it)
            send(it)
        }
    }

As I mentioned, I already tried map() which does the same under the hood. Two things I don't really like about this:
1. I need to pass capacity as map() creates produce(capacity = 0)
2. I'm creating several `Channel`s, which are passed as ReceiveChannel in one place and SendChannel in the other one, so I have to put this onEach specifically on ReceiveChannel side, which isn't very convenient.

So I'll probably stick with derivative class for debugging purposes for now.
