If I want to make a list observable, do I have to wrap this is a channel? I want to be notified whenever an item is added or removed from the list

val myList = mutableListOf<String>()

I don't think kotlin really has observable lists out of the box, you're probably going to have to roll your own wrapper or find a library, there's no easy "wrap in a channel"

also text book use case for using by delegate
