This project is essentially abandonware!
I may respond to minor issues, like version bounds which need changing, but I won't be doing any significant work.
Offer to take over the package if you want any significant changes.
The Monoid instance for Maybe behaves like so:
instance Monoid a => Monoid (Maybe a) where
mappend (Just x) (Just y) = Just $ x <> y
mappend (Just x) Nothing = Just x
mappend Nothing (Just y) = Just y
mappend Nothing Nothing = Nothing
mempty = Nothing
Both is a newtype wrapper around Maybe providing this instance:
instance Monoid a => Monoid (Both a) where
mappend (Just x) (Just y) = Just $ x <> y
mappend _ _ = Nothing
mempty = Just mempty
