$ cat README.md | skua "(flatMap (split /[^A-Za-z]/))
                        (filter (compose not (test /^$/)))
                        (map toLower)
                        (toArray)
                        (map (countBy identity))
                        (map (fanout (zipWith (sandwich \" \")) values keys))
                        (flatMap (sort naturalSort))
                        (take 4)"
