-.. tip::
+You can omit the index attribute (``key`` in the previous example) by setting
+the ``index_by`` attribute on the ``tagged_iterator`` tag. In this case, you
+must define a static method whose name follows the pattern:
+``getDefault<CamelCase index_by value>Name``.
+
+For example, if ``index_by`` is ``handler``, the method name must be
+``getDefaultHandlerName()``:
+
+.. code-block:: yaml
+
+    # config/services.yaml
+        services:
+            # ...
+
+            App\HandlerCollection:
+                arguments: [!tagged_iterator { tag: 'app.handler', index_by: 'handler' }]
 
-    Just like the priority, you can also implement a static
-    ``getDefaultIndexName()`` method in the handlers and omit the
-    index attribute (``key``)::
+.. code-block:: php
 
-        // src/Handler/One.php
-        namespace App\Handler;
+    // src/Handler/One.php
+    namespace App\Handler;
 
-        class One
+    class One
+    {
+        // ...
+        public static function getDefaultHandlerName(): string
         {
-            // ...
-            public static function getDefaultIndexName(): string
-            {
-                return 'handler_one';
-            }
+            return 'handler_one';
         }
+    }
 
-    You also can define the name of the static method to implement on each service
-    with the ``default_index_method`` attribute on the tagged argument:
