title: NoMethodError: undefined method `require' in rubyfiddle.com
body: <p><a href="http://rubyfiddle.com/" rel="nofollow noreferrer">http://rubyfiddle.com/</a> has some limitations on its usage, and it doesn't even let me require a gem. This code in my fiddle:</p>
  
  <pre><code>require 'net/http'
  </code></pre>
  
  <p>throws the error</p>
  
  <pre><code>NoMethodError: undefined method `require' for Object:Class
  </code></pre>
