Description 
Utilities related to Monad and Applicative classes
Mostly for backwards compatability.

 Methods    Instances  


mapAndUnzip3M :: Monad m => (a > m (b, c, d)) > [a] > m ([b], [c], [d]) 
mapAndUnzipM for triples


mapAndUnzip4M :: Monad m => (a > m (b, c, d, e)) > [a] > m ([b], [c], [d], [e]) 

mapAccumLM 
:: Monad m   => acc > x > m (acc, y)  combining funcction
 > acc  initial state
 > [x]  inputs
 > m (acc, [y])  final state, outputs
 Monadic version of mapAccumL



mapSndM :: Monad m => (b > m c) > [(a, b)] > m [(a, c)] 
Monadic version of mapSnd


concatMapM :: Monad m => (a > m [b]) > [a] > m [b] 
Monadic version of concatMap


anyM :: Monad m => (a > m Bool) > [a] > m Bool 
Monadic version of any, aborts the computation at the first True value


allM :: Monad m => (a > m Bool) > [a] > m Bool 
Monad version of all, aborts the computation at the first False value


foldlM :: Monad m => (a > b > m a) > a > [b] > m a 
Monadic version of foldl


foldrM :: Monad m => (b > a > m a) > a > [b] > m a
