Not a built-in, but... (defmacro for-each [f x] `(doseq [item# ~x] (~f item#))) I suppose this solution is blindingly obvious though. Also, I would be curious if there's any significant performance difference using (dorun (map ...)) as I assume an intermediate result is built and then thrown away. Or perhaps it's insignificant compared to what the unspecified function does that is passed to map for performing the side-effect work..
