 While Griffe will load this code without error, the `'Bar'` forward reference won't be resolved to the actual `Bar` class. As a consequence, downstream tools like documentation renderers won't be able to output a link to the `Bar` class. We therefore recommend to avoid using forward references in base classes, if possible.
 
-Instead, you can try to declare or import the `Bar` class earlier, or make `FooBar` generic again but with a default type:
+Instead, you can try one of the following approach:
 
-```python
-class Foo[T]:
