Very good point.  I didn't know about `symbol-name'.  I suggested
regular expression here because I use it in a macro, so the slowdown
only happens at compile time.  But I didn't want to scare Ted off with
the slightly more brackety version. ;-)

(defmacro Init-system-type-load (&rest args)
  "Evaluates to appropriate form based on `system-type'

Takes args in this way

  (Init-system-load (\"regex\" (form1a) (form1b)) (\"string2\"
(forms2a)))

t will match anything."
  (dolist (arg args)
    (when (or (eq (car arg) t)
              (string-match (car arg) (symbol-name system-type)))
      (return (cons 'progn (cdr arg))))))
