runPerm :: Alternative m => Perm m a -> m aSource

Unwrap a Perm, combining actions using the Alternative for f.

liftPerm :: m a -> Perm m aSource

A version of lift that can be used without a Monad for m.

liftPlus :: (forall a. m a -> m a -> m a) -> Perm m b -> Perm m b -> Perm m bSource

hoistPerm :: MonadFix n => (forall a. m a -> n a) -> Perm m b -> Perm n bSource

Lift a monad homomorphism from m to n into a monad homomorphism from Perm m to Perm n.
