The language encourages hierarchical organizations of processes (ACTORS) that communicate with messages. It is lamentable that the paper includes no reference to more extensive information on EPL.

    The interested reader may benefit from some additional references not included in the paper. The style of programming with classes and instances grew from SIMULA and more recently Smalltalk and ACTORS. Techniques similar to those in EPL that use messages to communicate with and synchronize distributed processes are described in CSP
