Here's an example from Stuart Halloway's book. (defmacro chain ([x form] (list '. x form)) ([x form & more] (concat (list 'chain (list '. x form)) more)))
(macroexpand '(chain arm getHand getFinger getNail) ; I added the getNail part. The result is (. (. (. arm getHand) getFinger) getNail) I'm having trouble understanding how this works. In the first call, x is arm, form is getHand, and more is '(getFinger getNail), right? I expected that more would be processed recursively, but it seems to me that only form is processed recursively. Somebody please straighten me out here. -- R.
