 A number of places check whether a user object has instantiated the data
 of an actual user by either checking whether the user object is empty or
 falsely. Both checks will fail to come to the correct conclusion because
 `$user` is an object that has default properties and methods.

 {{{
 $user = new WP_User( 0 ); // not a user's ID

 var_dump( empty( $user ) ); // false!
 var_dump( ! $user ); // false !
 var_dump( empty( $user->ID ) ); // true; that's more like it
 }}}
