title: Breakpoints with pry-byebug don't trigger in the console
body: <p>I'm trying to use pry and pry-byebug to step through the execution of some code in a Rails console. I started the console with </p>
  
  <p><code>pry -r ./config/environment</code></p>
  
  <p>I then set a breakpoint:</p>
  
  <p><code>break Foo#bar</code></p>
  
  <p>Then make a new <code>Foo</code> and call <code>bar</code> on it:</p>
  
  <p><code>Foo.new.bar</code></p>
  
  <p>I expected step into <code>Foo#bar</code>, but instead the method just executed normally.</p>
  
  <p>Is there some way to get this workflow to work? </p>
