We then show how to build reusable, composable distributed computing components in the new model. • We propose a programming model based on isolates, typed event channels and event streams. ...
Reactive isolates, proposed in this paper, simplify protocol composition with first-class typed channels and event streams. We compare reactive isolates and the actor model on concrete programs. ...
The model expresses concurrent computations with isolates, which use typed channels for inter-isolate communication, and event streams for intraisolate event propagation. ...

If, for instance, entire subroutines of legacy code can be plugged into the new structure, the investment required for the re-discovery of the details of what they do can be spared. ...
