Thanks. That works great for union and intersection, although I prefer threadLast over threadFirst for other reasons. The thing that motivated this line of thought is that we have some primitives that read from right to left and unlike union/intersection are order sensitive. (apply q2 q1) means for each result of q1, run q2 and return the results. For q1 = a->b()->c() and q2 = d->e()->f(), I'm trying to find an acceptable/natural thread last syntax. user=> (clojure.walk/macroexpand-all '(->> a b c (->> d e f (apply)))) (c (b a) (apply (f (e d)))) Is there a way we could end up with (apply (f (e d)) (c (b a))) -Arun -- You received this message because you are subscribed to the Google Groups "Clojure" group.
