Instances

(Arrow a, ArrowApply a) => Monad (ArrowAsMonad a)

An instance that lets you work with Arrows that support ArrowApply as monads. | Example: | myarrow :: ArrowApply a => a Int Int | myarrow = monadicA $ v -> do | let vp1 = v + 1 | v' <- unmonadicA anotherIntToIntArrow vp1 | return (v' * 10)

monadicA :: ArrowApply a => (b -> ArrowAsMonad a c) -> a b c

Embed a block of monadic code in an arrow.

unmonadicA :: ArrowApply a => a b c -> b -> ArrowAsMonad a c

Embed an arrow in a block of monadic code.

liftA :: Arrow a => (c -> d) -> a b c -> a b d

Lift an Arrow operation.
