title: Laravel Eloquent: eager loading of multiple nested relationships
body: <p>What laravel says:</p>
  
  <pre><code>$books = App\Book::with('author.contacts')-&gt;get();
  </code></pre>
  
  <p>What I need is something like this</p>
  
  <pre><code>$books = App\Book::with('author[contacts,publishers]')-&gt;get();
  </code></pre>
  
  <p>where we eager load multiple relationships within a relationship. </p>
  
  <p>Is this possible?</p>
