I'm pretty sure force is still causing the evaluation... Just indirectly :) The delay here is forced by its print method, which, as you can see, also prints the value. Delays could be changed to print something like #<de...@232aee0: not computed>, but I wonder if that's really useful. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
