When people say 'code is data' they obviously don't mean that source code is stored in a text file which consists of bytes... (def add (x y) (+ x a)) (def sub (x y) (- x y)) (add 1 2) # 3 (sub 1 2) # -1 (first '(add 1 2)) # 'add (rest '(add 1 2)) # (list 1 2) (apply 'sub (rest '(add 1 2))) # -1 (reverse '(add 1 2) # '(2 1 add) Excuse my pseudo lisp quote syntax, it's been a while.
