title: Eloquent column list by key with array as values?
body: <p>So I can do this with Eloquent:</p>
  
  <pre><code>$roles = DB::table('roles')-&gt;lists('title', 'name');
  </code></pre>
  
  <p>But is there a way to make Eloquent fetch an array of values for each distinct key instead of just one column?</p>
  
  <p>For instance, something like the following:</p>
  
  <pre><code>$roles = DB::table('roles')-&gt;lists(['*', DB:raw('COALESCE(value, default_value)')], 'name');
  </code></pre>
