title: Reload rails initializers
body: <p>In application.rb, I have </p>
  
  <pre><code>config.autoload_paths += %W(#{config.root}/lib 
  </code></pre>
  
  <p>So when I modify a class under lib, my code is reloaded.</p>
  
  <p>However, when I tried adding config/initializers to autoload, I noticed my code doesn't get updated.</p>
  
  <p>If I'm writing an extension for the string class, I have to restart rails every time I modify my code.</p>
  
  <p>Please advise?</p>
