While *every?* and *not-any?* return true or false, *some* returns the first truthy value in a sequence, or nil if there are none.
Similarly, *empty?* returns true or false, while *empty* and *not-empty*return a collection or nil. However, it seems as if* some*, *empty*, and *not-empty *are intended to be used like predicates, as well other ways. They are predicates in the Common Lisp sense. This makes me think that question marks are supposed to be reserved for functions that return booleans. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
