title: Ruby: Is there an opposite of include? for Ruby Arrays?
body: <p>I've got the following logic in my code:</p>
  
  <pre><code>if !@players.include?(p.name)
    ...
  end
  </code></pre>
  
  <p><code>@players</code> is an array.  Is there a method so I can avoid the <code>!</code>?</p>
  
  <p>Ideally, this snippet would be:</p>
  
  <pre><code>if @players.does_not_include?(p.name)
    ...
  end
  </code></pre>
