A modern programming language that makes developers happier.

kotlinlang

Is there a recommended <https://kotlinlang.org/docs/shared-mutable-state-and-concurrency.html#thread-safe-data-structures|thread safe data structure> to be used when you want to have a set of listeners that are called for certain actions, something that in JVM could be solved with `CopyOnWriteArraySet` ?
```private val actionListeners: MutableCollection&lt;ActionListener&gt; = CopyOnWriteArraySet()```

in practice I need it for JVM/Android and iOS

maybe the KMP alternative would be to use a `Channel` that emits `Action` instead of a `ActionListener`
