The terminology of Dreams2.1 is in parity with that of the Flavors [Moo86] OOP for the Symbolics Lisp Machines. The hardware of these machines is very similar to the hardware of Forth machines [Sym84,Koo89]. Lisp was a very strong influence on the design of the Forth language. Charles Moore, the inventor of Forth, took a graduate course in Lisp at MIT from John McCarthy himself, the inventor of Lisp, before starting to design Forth2.2.
