Regular functions have this clever ability to have their variadic arguments applied lazily:
user=> (defn z [a & r] "zero") #'user/z user=> (apply z (iterate inc 0)) "zero" Since the z function ignored the r sequence, apply didn't bother walking down the infinite sequence at all. Multimethods don't have this same feature: user=> (defmulti z (fn [a & r] a)) #'user/z user=> (defmethod z 0 [a & r] "zero") [EMAIL PROTECTED] user=> (z 0) "zero" user=> (apply z (take 100 (iterate inc 0))) "zero" So good so far -- the r argument works as expected. But if we give it an infinite sequence, it gets stuck in an infinite loop: user=> (apply z (iterate inc 0)) ; never comes back You have been warned. :-) --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
