Charles Duff. An object-oriented extension of FORTH, for the Mac. Inheritance, SANE floating point, system classes and objects for Mac interfacing, overlays. Sold by Kriya Systems, 1985-1988. Modified, made PD and renamed Yerk.

from Rodriguez & Poehlman:
Neon was a commercial OOF, modeled after Smalltalk; when released into the public domain it was renamed Yerk. The object is not executed; it is parsed by the message word, which invokes or compiles the method. Added data structures include: class definition header, class list, method list, method stack, and object stack. Objects are statically allocated, but dynamically allocated memory can be "cast" as objects.
