I'm working on a webcomic framework for fun when I ran into the following problem:

gistfile1.txt

(import hypertext)
(import sqlite3 :as sql)
(import ./src/data-access :as da)
(import ./src/data-presentation :as dp)
(import ./src/debug :as dbg)

#goes to dp:
(defn render-contents--works [page-contents]
  (defn make-html [content]
    (let [image-url (string "/blob/" (content :blobid))]
      (hypertext/from-data
        ~(img {:src ,image-url}))))
  (def sorted-contents (sorted-by |($ :position) page-contents))
  (map make-html sorted-contents))

(defn render-contents--doesnt [page-contents]
  (def sorted-contents (sorted-by |($ :position) page-contents))
  (map |(let [image-url (string "/blob/" ($ :blobid))]
          (hypertext/from-data
            ~(img {:src ,image-url})))
       sorted-contents))
