hi guys! i'm going to implement coroutined version of

list.forEachIndexed

. i need the items order to be preserved, but each item should be processed in a separate thread (pool of 4 threads). is it a good idea to implement it via channels?

You can create four coroutines, all receiving from the same channel. Send all the work you need them to do to this channel. This pattern is known as "worker pool".
