title: Ruby: How to run irb immediately after running ruby file externally?
body: <p>Is there a way to load a ruby file from terminal, but continue coding dynamically after?</p>
  
  <p>Example:</p>
  
  <pre><code>$ ruby some_file.rb
  
  # ... code from source file ...
  </code></pre>
  
  <p>and continue coding from here through terminal (in the same fashion as irb)?</p>
