/**
 * Static Service Container wrapper.
 *
 * Generally, code in Drupal should accept its dependencies via either
 * constructor injection or setter method injection. However, there are cases,
 * particularly in legacy procedural code, where that is infeasible. This
 * class acts as a unified global accessor to arbitrary services within the
 * system in order to ease the transition from procedural code to injected OO
 * code.
 *
 * The container is built by the kernel and passed in to this class which stores
 * it statically. The container always contains the services from
 * \Drupal\Core\CoreServiceProvider, the service providers of enabled modules and any other
 * service providers defined in $GLOBALS['conf']['container_service_providers'].
 *
 * This class exists only to support legacy code that cannot be dependency
 * injected. If your code needs it, consider refactoring it to be object
 * oriented, if possible. When this is not possible, for instance in the case of
 * hook implementations, and your code is more than a few non-reusable lines, it
 * is recommended to instantiate an object implementing the actual logic.
 *
 * @code
 *   // Legacy procedural code.
 *   function hook_do_stuff() {
 *     $lock = lock()->acquire('stuff_lock');
 *     // ...
 *   }
 *
 *   // Correct procedural code.
 *   function hook_do_stuff() {
 *     $lock = \Drupal::lock()->acquire('stuff_lock');
 *     // ...
 *   }
 *
 *   // The preferred way: dependency injected code.
 *   function hook_do_stuff() {
 *     // Move the actual implementation to a class and instantiate it.
 *     $instance = new StuffDoingClass(\Drupal::lock());
 *     $instance->doStuff();
 *
 *     // Or, even better, rely on the service container to avoid hard coding a
 *     // specific interface implementation, so that the actual logic can be
 *     // swapped. This might not always make sense, but in general it is a good
 *     // practice.
 *     \Drupal::service('stuff.doing')->doStuff();
 *   }
 *
 *   interface StuffDoingInterface {
 *     public function doStuff();
 *   }
 *
 *   class StuffDoingClass implements StuffDoingInterface {
 *     protected $lockBackend;
 *

 *       $this->lockBackend = $lock_backend;
 *     }
 *
 *     public function doStuff() {
 *       $lock = $this->lockBackend->acquire('stuff_lock');
 *       // ...
