You seem to be confused about what true? and false? are intended to do. +user=> (doc true?) ------------------------- clojure.core/true? ([x]) Returns true if x is the value true, false otherwise. nil +user=> (doc false?) ------------------------- clojure.core/false? ([x]) Returns true if x is the value false, false otherwise. nil
