With paredit.vim, put cursor on `output-queue-map` and hit "dab". Very strange things happen and undo doesn't even undo them. please read files in order: before.clj, after.clj, after-undo.clj.

after-undo.clj

(defn foo
  [context]  (wrap-router 
  (wrap-router (comp output-queue-map
                     (routing-table %)
                     :type)))

after.clj

(defn foo
  [context]  (wrap-router 

before.clj

(defn foo
  [context]
  (wrap-router (comp output-queue-map
                     (routing-table %)
                     :type)))
