title: How to monkey patch Numeric in config/application.rb file
body: <p>I would like to know if it's possible to monkey patch the Numeric DSL in the <code>config/application.rb</code> file. I'm trying to with:</p>
  
  <pre><code>Numeric.include CoreExtensions::Numeric
  </code></pre>
  
  <p>At the end of the file. But when I try to run the local server I see:</p>
  
  <pre><code>NameError: uninitialized constant CoreExtensions
  </code></pre>
  
  <p>The CoreExtensions namespace exists within <code>app/lib/core_extensions</code>.</p>
  
  <p>Thanks.</p>
