insert :: Ord a => a -> Set a -> T a Source #

We cannot have a reasonable instance Insert Set, since the instance Insert (NonEmpty Set) would preserve duplicate leading elements, whereas Set does not.

However, the instance Insert NonEmpty is not the problem. A general type like

insertSet :: (Insert f, Ord a) => a -> f a -> NonEmpty f a

cannot work, since it can be instantiated to

insertSet :: (Ord a) => a -> NonEmpty Set a -> NonEmpty (NonEmpty Set) a

and this is obviously wrong: insertSet x (singleton x) has only one element, not two.
