While my CDP class didn't explicitly discuss the Actor Model, message-passing as a concurrency model was studied and we did implement algorithms using it. How basic is the Actor Model for implementing concurrency using message-passing, besides the obvious advantage of formally defining a common language of terms and proven theorems for what you're doing?
