What's the cleanest way to run a piece of code if any branch of a cond statement succeeded, without relying on the return value of the individual clauses not to be nil?
For example, if I have the following piece of code that says I can only move left or up (cond (= dir :left) (move-left) (= dir :up) (move-up)) but (move-left) or (move-up) could themselves return nil, is there any nice way to check if one of them was called? martin -- You received this message because you are subscribed to the Google Groups "Clojure" group.
