What is an Actor?
A [Syndicated Actor][Actor] is a collection of stateful [Entities][Entity], organised in a tree of [Facets][Facet], with each facet representing a (sub)conversation that the Actor is engaged in. Each entity belongs to exactly one facet; each facet has exactly one parent and zero or more children; each actor has exactly one associated root facet. When a facet is its actor's root facet, its parent is the actor itself; otherwise, its parent is always another facet.
In the taxonomy of De Koster et al. (2016), the Syndicated Actor model is a Communicating Event-Loop actor model, similar to that offered by the E programming language (Wikipedia; erights.org).
