I'm somewhat new to clojure and trying to understand mapcat, so apologies in advance if this is an embarrassingly elementary question.
mapcat's signature is (f & colls) which indicates to me I should be able to so something like (mapcat #(list (inc %)) [1 2 3] [4 5 6]). That is, doesn't the & indicate that I can pass in a variable number of colls? However, if I do, it crashes and burns, since internally it's calling (apply map #(list (inc %)) '([1 2 3] '[4 5 6])), which, as expected, throws an ArityException. So, am I missing something or is mapcat's signature wrong? It seems to me it should be (f colls) and not (f & colls). -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
