I haven't played around with atomicity, but wouldn't it be cool if this worked?

  (atomic (def enq (obj q) ...)
      (def deq (q) ...))
Edit: if I'm testing properly, this doesn't work:

  arc> (atomic (def wait () (sleep 5) (prn "done with wait")) (def stuff () (prn "stuff!")))
  #<procedure: stuff>
  arc> (thread (wait))
  #<thread>
  arc> (stuff)
  stuff!
  "stuff!"
  arc> done with wait

I thought about this too, but it doesn't look right to me. I would expect this makes the act of defining the functions atomic, but not calls to those functions once defined.

To me, it feels the same as

  (let ctr 0
       (def inc () (++ ctr))
       (def reset () (= ctr 0))
