You can't use Laravel Facades in Illuminated WordPress Plugins

   * You can't use the DB Facade, even though this would be syntactically
   * valid in Laravel—the reason is that unlike in a Laravel App, in
   * WordPress, there's potentially more than one Container per request—
   * so the Facades can't know which Container they should ask to get 
   * the referenced component. Sorry!
