DrupalX keeps everything under one single namespace. So you'll never again have to remember the exact order and capitalization of namespaces. Was it Drupal\node\Node or Drupal\Entity\node\Node or Drupal\node\Entity\Node? Confusing. To say the least. Not anymore! DrupalX uses one unified single namespace which is simply Drupal\drupalx. This means that you can now easily "use" all of the DrupalX classes you need in one go - simply by leveraging the namespace grouping syntax of PHP7 :
use Drupal\drupalx\{Node,Form,Menu,Mail};
