Clojure rename loaded libraries

Question

Is there any way to rename clojure libraries when you load them with require or use?

For example, is there any way to do something like

(require 'some.include.path.some-library :as something-else)

and then reference elements of some-library through something-else/element-name?

Thanks.

Take a look at http://clojure.org/libs :

A simple lib with embedded explanations:

(ns com.my-company.clojure.examples.my-utils
  (:import java.util.Date)
  (:use [clojure.contrib.def :only (defvar-)])
  (:require [clojure.contrib.shell-out :as shell]))

• The ns form names the lib's namespace and declares its dependencies. Based on its name, this lib must be contained in a Java resource at the classpath-relative path: com/my_company/clojure/examples/my_utils.clj (note the translations from period to slash and hyphen to underscore).
• The :import clause declares this lib's use of java.util.Date and makes it available to code in this lib using its unqualified name.
• The :use clause declares a dependency on the clojure.contrib.def lib for its defvar- function only. defvar- may be used in this lib's code using its unqualified name.
• The :require clause declares a dependency on the clojure.contrib.shell-out lib and enables using its members using the shorter namespace alias shell.
