GHC.Internal.Control.Monad.Zip

Monadic zipping (used for monad comprehensions)

  • 1 class
classclass Monad m => MonadZip (m :: Type -> Type) where
#

Instances should satisfy the laws:

Naturality
liftM (f Control.Arrow.*** g) (mzip ma mb)
    = mzip (liftM f ma) (liftM g mb)
Information Preservation

liftM (Prelude.const ()) ma = liftM (Prelude.const ()) mb implies munzip (mzip ma mb) = (ma, mb)

Methods

  • mzip :: m a -> m b -> m (a, b)
  • mzipWith :: (a -> b -> c) -> m a -> m b -> m c
  • munzip :: m (a, b) -> (m a, m b)
