For me, one of the hardest things about clojure has been learning how to mangle the results from one function into the format expected by another: vectors, nested lists, etc. There are many core functions to help: reduce, apply, map, etc. But there are many of them because each one applies to a different situation. I think that complexity is necessary and even useful, but quick tips like these are helpful.
