Using "box of punch cards" as REPL, "punch card machine" as 'solo cpu' and "device operator" as handler for everything else. Lisp just does the punch card box. Scheme does "the box" with access to the "punch card machine" and emacs covers the whole REPL, 'solo cpu', 'device operator' stuff So, common lisp needs a 'device operator' namespace.
