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
