Why does require in the ns form behave different from the require function

Question

When I require libraries from the ns form I get :

test> (ns test (:require \'(clojure.contrib [logging :as log] [sql :as sql]) ))
lib names inside prefix          


        

Answer 1

The ns form is a macro, and so it doesn't require that you use ' to quote the provided seq.

An example from the Clojure docs:

(ns foo.bar
    (:refer-clojure :exclude [ancestors printf])
    (:require (clojure.contrib sql sql.tests))
    (:use (my.lib this that))
    (:import (java.util Date Timer Random)
       (java.sql Connection Statement)))
