Ah, reader macro! Thanks! Ignore next form (#_) The form following #_ is completely skipped by the reader. (This is a more complete removal than the *comment* <http://clojure.github.io/clojure/clojure.core-api.html#clojure.core/comment> macro which yields nil). (from *http://clojure.org/reader* <http://clojure.org/reader>) Conclusion: Don't use the *comment* <http://clojure.github.io/clojure/clojure.core-api.html#clojure.core/comment> macro. It makes runtime overhead.
