This module provides some convenient functions for dealing with Booleans.

The most important one being `bool`

, a function that can be used in place of
the build-in `if then else`

-syntax.

- bool :: a -> a -> Bool -> a
- mwhen :: Monoid a => a -> Bool -> a
- mwhenM :: (Monad m, Monoid a) => m a -> Bool -> m a
- whenA :: Arrow a => a b b -> Bool -> a b b
- whenC :: Category cat => cat a a -> Bool -> cat a a
- whenM :: Monad m => (a -> m a) -> Bool -> a -> m a
- type BoolAlgebra r = (r, r)
- cata :: BoolAlgebra r -> Bool -> r
- ana :: (b -> Bool) -> b -> Bool

# Main function

# Morphisms

type BoolAlgebra r = (r, r)Source

cata :: BoolAlgebra r -> Bool -> rSource

Catamorphism for booleans.
