Does anyone know how if in #Python it is possible to define a generic class that infers the type of the generic from an attribute?

Something like this:

```
T = TypeVar("T")
class Example(Generic[T]):
Config: type[T]
configuration: T

class SubExample(Example):
Config = str

reveal_type(SubExample().configuration)
```

currently Pylance and Mypy complain about Example not being passed the TypeVar, I wonder if there's a different way to achieve this 👀
