I like to maintain the fact that Arc's '+ is left-associative

Good work!

if 'treewise could tell that it had a cyclic data structure, it would also be a more robust option

Do you mean cyclic structure like this?

  arc> (= xs (list 1))
  (1)
  arc> (do1 nil (= (cdr xs) xs))
  nil
  arc> (xs 1000)
  1
Never thought of that. I mean, the P part of the vanilla Arc REPL breaks on them, and I've never been compelled to use cycles. When are cyclic lists used? I guess if you're representing certain graphs?

In a more general sense, I wear my opinion about treewise on my sleeve: http://arclanguage.org/item?id=12115.
