title: How to use rest parameters in tuple?
body: <p>In TypeScript 3 was appeared this opportunity to use rest parameters in tuple.</p>
  
  <p>I tried this like:</p>
  
  <pre><code>type Coordinate = [number, number, ...number[]];
  
  let coordinats: Coordinate;
  
  coordinats = [1, 2, 3,4];
  
  console.log(coordinats[2]);
  </code></pre>
  
  <p>Why <code>console.log(coordinats[2]);</code> does not return me 3 and 4?</p>
