title: Match a pattern in an array
body: <p>There is an array with 2 elements</p>
  
  <pre><code>test = ["i am a boy", "i am a girl"]
  </code></pre>
  
  <p>I want to test if a string is found inside the array elements, say:</p>
  
  <pre><code>test.include("boy")  ==&gt; true
  test.include("frog") ==&gt; false
  </code></pre>
  
  <p>Can i do it like that?</p>
