 We can probably add some helper functions that complete common tasks
 around Superglobal access

 Examples of accessing here:
 https://codeclimate.com/github/WordPress/WordPress/wp-admin/edit-
 comments.php

 Something like `wp_verify_action( $action )` could replace the many
 instances of things like:
 `isset( $_REQUEST['action'] ) && 'upload-attachment' ==
 $_REQUEST['action']`

 Without having to architect something like `Symfony/HttpFoundation`, we
 can make accessing them more rare.
