  1. mapM_ :: forall t k o f a b u . (Foldable t k k, WellPointed k, Monoidal f k k, u ~ UnitObject k, ObjectPair k (f u) (t a), ObjectPair k (f u) a, ObjectPair k u (t a), ObjectPair k (t a) u, ObjectPair k (f u) (f u), ObjectPair k u u, ObjectPair k b u, Object k (f b)) => k a (f b) -> k (t a) (f u)

    constrained-categories Control.Category.Constrained.Prelude

    The distinction between mapM_ and traverse_ doesn't really make sense on grounds of Monoidal / Applicative vs Monad, but it has in fact some benefits to restrict this to endofunctors, to make the constraint list at least somewhat shorter.

  2. mappend :: Monoid a => a -> a -> a

    constrained-categories Control.Category.Constrained.Prelude

    An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.

  3. mapM :: (Traversable t, Monad m) => (a -> m b) -> t a -> m (t b)

    copilot-language Copilot.Language.Prelude

    Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.

    Examples

    mapM is literally a traverse with a type signature restricted to Monad. Its implementation may be more efficient due to additional power of Monad.

  4. mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()

    copilot-language Copilot.Language.Prelude

    Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results. For a version that doesn't ignore the results see mapM. mapM_ is just like traverse_, but specialised to monadic actions.

  5. mappend :: Monoid a => a -> a -> a

    copilot-language Copilot.Language.Prelude

    An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.

  6. type family MapSub (e :: k) (xs :: [Type]) :: [Type]
