+        Rector\Rector\MagicDisclosure\GetAndSetToMethodCallRector:
+            # class
+            'Nette\DI\Container':
+                # magic method (prepared keys): new real method
+                'get': 'getService'
+                'set': 'addService'
+    ```
+    
+    This will change:
+    
+    ```php
+    $result = $container['key'];
