API docs for the arguments to apply - "([f args* argseq])"; so the following is perhaps more straight-forward: (apply str (seq [1 2 3])) => "123" Additionally, the following works too in Cloure 1.0.0: (apply str [1 2 3]) => "123" ...though it does not follow from the API docs, which imply that the last argument to apply should be seq, and "(seq? [1 2 3])" => false. -Dave -- You received this message because you are subscribed to the Google Groups "Clojure" group.
