I often encountered the case, that I want to do an apply in the -> or eg. some filter or map, which also does not work. But maybe you are right, and this is a sign that the code is bad. Nevertheless here a combined version, which does not need to specify the _ all the time. (defmacro >> [x & forms] `(let ~(apply vector '_ x (mapcat (fn [form] (if (seq? form) (if (some #(= '_ %) form) (list '_ form) (list '_ (list* (first form) '_ (rest form)))) (list '_ (list form '_)))) forms)) ~'_)) Sincerely Meikel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
