I wrote something like this too. I called mine >>_ and used _ as the insert mark. Here's my implementation: (defmacro >>_ [& exprs] (list 'let (apply vector (mapcat (fn [expr] (list '_ expr)) exprs)) '_ )) user=> (>>_ "Hello" (apply str _ [", " "World!"])) "Hello, World!" I used it a couple times after first writing it, but have since failed to find much use for it. I guess I wouldn't really recommend it. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
