I went over this quickly, though it seems to work OK:
(defn threading [x first? forms]
(reduce
(fn [x form]
(if (seq? form)
(let [[op & args] form
args (conj (cond-> args (not first?) vec) x)]
(apply list op args))
(list form x)))
x forms))
(defmacro -> [x & forms]
(threading x true forms))
(defmacro ->> [x & forms]
(threading x false forms))
Take care,
Moe
