This makes the type more informative and general - closer to how the function behaves, particularly in isolation.

    toExtension ::: (a | a -> a | a -> a -> a) -> a -> a -> a

    a = AttrSet & !Function

    toExtension ::

      b' -> Any -> Any -> b'

    or

    toExtension ::

      (a -> b') -> Any -> a -> b'

    or

    toExtension ::

      (a -> a -> b) -> a -> a -> b

    where b' = ! Callable



    Set a = b = b' = AttrSet & ! Callable to make toExtension return an extending function.

    ```
