The right way is putting the pipe operator at the beginning of the expression. (-> (gather-some-data) (map 'Vector #'some-functor) (filter #'some-predicate) (reduce #'some-gatherer)) Or for those who have an irrational fear of brackets: -> gather-some-data map 'Vector #'some-functor filter #'some-predicate reduce #'some-gatherer
