The best approach (for me) is always using the same symbol as a template placeholder, I like to think of it as "x marks the spot". Yes, it does require a new mind-crutch, specific to just that form, but I came to like it almost instantaneously---especially if you need to use x in more than one place within a threading step. If Clojure started out with just as->, it may have never occurred to anybody to ask for -> and ->>. -Marko -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
