Reloading lein repl

So, I'm working through the book Seven Web Frameworks in Seven Weeks from the awesome Pragmatic Programmers and I'm on the Clojure section (keep in mind that I don't know Clojure ^^) but quitting/restarting to get the repl to pick up changes just plain sucks.

Here's a solution I found on SO:

Add tools.namespace to your project.clj dependencies.

e.g.

:dependencies [
  # ...
  [org.clojure/tools.namespace "0.2.4"]]

After you start up the lein repl:

user=> (use '[clojure.tools.namespace.repl :only (refresh)])
nil

... make some changes to a clj file ...

user=> (refresh)
:reloading (hello.core hello.core-test zap.models)
:ok

It's not 100% automatic, but it beats quitting/restarting. Though it does appears you have to type that use statement every time after you refresh...
