Writing complex actors

I need to create a complex actor using some private methods to update the internal state, but I cannot find any useful base class to implement ActorJob.

What is the best practice in such case?

We are starting a new project and Actors model fits perfectly. I wonder that using Kotlin Actors requires to mark all code with @ObsoleteCoroutinesApi.

Do we have any progress on the actors implementation replacement?

What is your suggestion for those who want to use actors in the meantime (until actors come out of the experimental stage)? I’m currently working on a multiplatform library, so using coroutines to enable concurrency is very convenient, but I’m a bit puzzled about the best way (currently) to go about implementing something like a complex actor in your examples (A class which has suspending functions which work on shared mutable state).
