title: Pry-rails not reloading correctly
body: <p>When I enter <code>reload!</code> in my Rails console using <code>pry-rails</code>, it doesn't appear to be working; i.e., the changes I made to my code aren't implemented. Everything I've read seems to say that the <code>pry-rails</code> gem implements <code>reload!</code> all on its own.</p>
  
  <p>Here's how I test it: (I put <code>Deal.hello</code> in my code between pry lines 1 &amp; 2)</p>
