;; Middleware is a way to define a stack of operations applied to a function
;; call. It's a common pattern for parsing and handling http requests. A
;; handler function is wrapped by a middleware function. Let's narrow in on
;; http handling, then:

;; Let's call a 'handler function' a function that accepts as its input a
;; request, and returns a response.

(defn my-handler-fn [request]
  {:status 200 :body "42"})
