+Service Closures
+================
+
+This feature wraps the injected service into a closure allowing it to be
+lazily loaded when and if needed.
+This is useful if the service being injected is a bit heavy to instantiate
+or is used only in certain cases.
+The service is instantiated the first time the closure is called, while
+all subsequent calls return the same instance, unless the service is
+:doc:`not shared </service_container/shared>`::
+
+    // src/Service/MyService.php
+    namespace App\Service;
+
+    use Symfony\Component\Mailer\MailerInterface;
+
+    class MyService
+    {
+        /**
+         * @var callable(): MailerInterface
+         */
+        private \Closure $mailer;
+
+        public function __construct(\Closure $mailer)
+        {
+            $this->mailer = $mailer;
+        }
+
+        public function doSomething(): void
+        {
+            // ...
+
+            $this->getMailer()->send($email);
+        }

+        {

 This can typically be the case in your controllers, where you may inject several
 services in the constructor, but the action called only uses some of them.
 Another example are applications that implement the `Command pattern`_
