Or, in this case, ->>:

  (def lols (->> strs
                 (filter #(re-find #"LOL" %))
                 (map upper-case)
                 sort))

How I read it: take strs, filter the strings that contain "LOL", turn them into upper case and then sort them. Basically it reads the same as the pipeline example in the README.
