title: Laravel: Variables in localization strings
body: <p>I want to localize my app, but I got a problem:</p>
  
  <p>If I call the trans function like this: <code>{{ __('permission.addUser') }}</code>, the output is </p>
  
  <blockquote>
    <p>Add new user</p>
  </blockquote>
  
  <p>If I call <code>{{$permissions[13]}}</code> the output is </p>
  
  <blockquote>
    <p>addUser</p>
  </blockquote>
  
  <p>But if I mix them: <code>{{ __('permission.$permission[13]') }}</code>, the output is </p>
  
  <blockquote>
    <p>permission.$permissions[13]</p>
  </blockquote>
  
  <p>What's missing? What I did wrong?</p>
