No. (:require [protege.core :refer :all]) does roughly the following * Loads and compiles proteger.core * Stores it in the namespace map as proteger.core, so fn1 in it can be referred to with the ns prefix, proteger.core/fn1 * For every function in proteger.core, creates an alias in the current namespace (so they can be referred to without the ns prefix, e.g. fn1) This is exactly what :use was used for before Clojure 1.4. This approach is known as "naked :use" has a few issues * It makes it dead easy to override other functions in the current namespace, such as those of clojure.core, and not notice or ignore the warning * It is not obvious where does the function come from (:require protege.core) only loads the namespace but does not perform the 3rd step. If you want to spare some typing or make some code that uses a DSL look nicer, you can load a namespace with an alias (:require [protege.core :as p]) and then refer to it using the shorter prefix, e.g. p/fn1.
