Maybe you might find this useful

(defmacro ->
        ([x] x)
        ([x form] (if (seq? form)
                      (with-meta (replace {:? x} form) (meta form))
                      (list form x)))
        ([x form & more] `(-> (-> ~x ~form) ~@more)))

This allows for a more flexible threading operation:

user> (-> "c"
              (third-param "a" "b" :? "d")
              println)
first a second b third c fourth d
nil

Cheers
