You've prevented X from being evaluated (it will be seen as the symbol X), but you haven't prevented evaluation of the function call. Symbols happen to be functions that look themselves up in collections. 'Y is not a collection, so it returns nil. Had you had something else in function position that wasn't actually a valid function, you would have gotten a ClassCastException. jack. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
