title: Julia: does an Array contain a specific sub-array
body: <p>In julia we can check if an array contains a value, like so:</p>
  
  <pre><code>&gt; 6 in [4,6,5]
  true
  </code></pre>
  
  <p>However this returns false, when attempting to check for a sub-array in a specific order:</p>
  
  <pre><code>&gt; [4,6] in [4,6,5]
  false
  </code></pre>
  
  <p>What is the correct syntax to verify if a specific sub-array exists in an array?</p>
