I'm a clojure noob and im playing around with the language; made this fn to
have a taste of a couple of features. I think it's pretty concise but i'm
probably doing something "not the clojure way", So if you can teach me a
couple of things please go ahead ;D
(defn say_hello
([names] (say_hello names []))
([names saluted]
(if (some #{(first names)} saluted)
(println "Welcome Back" (first names) "!")
(println "Hello" (first names) "!"))
(if (empty? (rest names))
(println "Goodbye")
(say_hello (rest names) (cons (first names) saluted)))))
(say_hello ["Peter" "Pablo" "John" "Peter"])
; Hello Peter !
; Hello Pablo !
; Hello John !
; Welcome Back Peter !
; Goodbye
; nil
