Aaaah! :) My math books say booleans can't be true and false in the same time. I made a mistake assuming that the identity function just because it exists somewhere as an object in the memory is of a boolean type and as such it's boolean value is true. Well, everybody here - thank you!
Just for the record: The type of: - function 'identity' is "function with type signature: Any -> Any" - functions: 'true?, false?, not' is "function with type signature: Any -> Boolean" So following evaluations are perfectly valid: (true? identity) -> false (false? identity) -> false (not identity) -> false These functions should not be expected produce the boolean opposite of each other's result, even if it's a bit strange at the first glance. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
