There's a difference between iterative design of that nature and
initial design. An initial clean design is a good basis for further
iterative design; a messy initial design means backward compatibility
shackles you. "Originally designed" is different from "constantly
But Lisp has enough variants that the backward compat issue isn't as
major. There's no specific need for Scheme to maintain every mistake
of Common Lisp, or Clojure to support everything that elisp does.
