Yeah, but more and more I'm finding that with complex code, it can be rather difficult to identify the parts that are lazy and the parts that aren't. Which makes using binding rather risky. I've started to refactor most of my code to avoid dynamic binding, because I'm tired of getting burned by this gotcha. Which is a shame. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
