An actor is:
1. A lightproc, which, per my understanding, are async-spawned threads returning (optional?) Futures [0].
2. A ProcHandle [1] that lets you define process-state (like pid), control process-exec (like cancel, suspend?), listen on progress of a given lightproc that is run by BastianExecutors [2], whilst the message passing / supervisor semantics is handled by Bastion [3].
https://akka.io/ on JVM would be a better comparison to this than BEAM's implementation of actors, I think.
