I see. Also, I know the Self papers referenced some Smalltalk projects 
that used protos, but I checked those papers out and they reference 
Leiberman's papers on Actors. So maybe the geological record of protos 
looks like:

LISP and Simula --> Smalltalk and Frames --> Actors -> Smalltalk proto 
projects -> Self -> NewtonScript/JavaScript/Others
