```clojure (ns my-app.entry (:require [clojure.spec.alpha :as s] [clojure.repl :refer [doc]])) ;; the :: macro will automatically prepend current namespace into ;; the qualified :entry-state spec keyword (s/def ::entry-state #{:entered :exited}) ;; check it out: (doc :my-app.entry/entry-state) ;; ------------------------- ;; :my-app.entry/entry-state ;; Spec ;; #{:entered :exited} ```
