Hey, it's a Lisp! You can use almost any syntax you want. How about %1, %2, %3:
(defn re-do [f regex input]
(apply f (rest (re-find regex input))))
(re-do #(do-stuff-with %3 %1 %2) regex input)
Or even
(defmacro re-let [names regex input & body]
`(let [[_ ~@names] (re-find ~regex ~input)]
~@body))
(re-let [year month day] date-regex line
(do-something-with year month day))
This one doesn't even have the bug that gaz jones's let has. ;)
