title: Create an array from a tuple
body: <p>I can create an array from a tuple like this:</p>
  
  <pre><code>let a = (1, 2, 3);
  let b = [a.0, a.1, a.2];
  </code></pre>
  
  <p>Is there a way to do it without naming each element of the tuple? Something like:</p>
  
  <pre><code>let b = a.to_array();
  </code></pre>
