> Duplicate instance declarations:

it appears that there is (or was?) no way to hide instance definitions:


however looking at the exercise:

"... implement Functor instances for Either e, ((,) e), and
((->) e).”

does this not suggest

1) instance Functor Either e, ((,) e)
2) instance Functor Either e, ((->) e)
