title: Array type using Array<T> is forbidden
body: <p>My Ttslint throws a warning with this construction (<em>Array type using Array is forbidden. Use T[] instead (array-type)</em> ):</p>
  
  <pre><code>Array&lt;string | null&gt; | null
  </code></pre>
  
  <p>Is this correct replacement to the previous one?</p>
  
  <pre><code>(string | null)[] | null
  </code></pre>
