(def commands (condp = cmd
                  "abc" (println "ABC")
                  "def" (println "DEF")
                  "ghi" (println "GHI")))

(let [[cmd & args] (split message #" ")]
  commands)
;; When 'commands' is evaluated in this context it will not pick up
;; on 'cmd' being defined in the current context.

; Questions:
;; How should one go about splitting out a condp into a def or defn?

;; What about the pairs inside the condp?
;;; For instance, what is the preferred method of extracting
;;; the conditions "abc", "def", and "ghi" into their own def?
;;; They need structure if this is the case, no?
