Hooke your functions!

(defn examine [x] (println x))

(defn microscope "The keen powers of observation enabled by Robert Hooke allow for a closer look at any object!" [f x] (f (.toUpperCase (str x))))

(defn doubler [f & args] (apply f args) (apply f args))

(defn telescope [f x] (f (apply str (interpose " " x))))

(add-hook #'examine #'microscope) (add-hook #'examine #'doubler) (add-hook #'examine #'telescope)

;; Now when we examine something: (examine "something")

S O M E T H I N G S O M E T H I N G

Use the add-hook function to wrap a function in your a hook.

add-hook

(add-hook target-var f)
(add-hook target-var key f)

Add a hook function f to target-var. Hook functions are passed the target function and all their arguments and must apply the target to the args if they wish to continue execution.
