> John McCarthy wrote 6 easy things in machine code
It was actually Steve Russel, McCarthy's grad student, who had the idea of writing McCarthy's eval function in machine code.
I seem to recall reading that McCarthy was actually surprised to discover that Lisp _could_ be run by a real computer; he intended it to be a completely theoretical tool.
WTG putting this message together, good luck!
Well, I'm 42 and I believe I'm 20... until I spend any time hanging around 20 year olds.
