newLISP the true champion of homoiconicity

Can your Lisp do this, /prog/?

(define (plus-minus a b)
  (begin
    (setf (nth '(1 2 0) plus-minus) (if (= (nth '(1 2 0) plus-minus) -) + -))
    (+ a b)))

(plus-minus 10 2)
8
(plus-minus 10 2)
12

newLISP treats code literally as data unlike Common Lisp or Scheme.

Lispers have historically strived to make their Jewish Kabbalah magickz both efficient and versatile, and both the intent and the knowledge required to do so is what has set them apart from the scripting languages ``BDFL''s who designed pretty languages with shit semantics and performance.
