Now that currentScope { } is deprecated, should I use its implementation, CoroutineScope(coroutineContext) instead?
I have some code relying on it:

suspend inline fun <E> ReceiveChannel<E>.doOnEach(
        context: CoroutineContext = EmptyCoroutineContext,
        noinline action: suspend (E) -> Unit
) = currentScope {
    launch(context) { consumeEach { action(it) } }
}

that would become:

suspend inline fun <E> ReceiveChannel<E>.doOnEach(
        context: CoroutineContext = EmptyCoroutineContext,
        noinline action: suspend (E) -> Unit
) = CoroutineScope(coroutineContext).launch(context) { consumeEach { action(it) } }

That is one option. Alternative is to write GlobalScope.launch(coroutineContex) It looks more explicit to me and is slightly more efficient (one object less)..

We’ll be addressing channels and their integration with structured concurrency is a separate effort.

I used GlobalScope.launch(coroutineContext + context).
