Documentation
(<=<) :: Monad m => (b -> m c) -> (a -> m b) -> a -> m c infixr 1 Source #
Also present in newer versions of the base package.
untilM :: Monad m => (a -> Bool) -> m a -> m a Source #
Deprecated: use M.until
repeat action until result fulfills condition
iterateLimit :: Monad m => Int -> (a -> m a) -> a -> m [a] Source #
parameter order equal to that of nest
iterateLimitM :: Monad m => Int -> (a -> m a) -> a -> m [a] Source #
Deprecated: use M.iterateLimit
parameter order equal to that of nest
iterate :: Monad m => (a -> m a) -> a -> m [a] Source #
I think this makes only sense in a lazy monad
like Trans.State.Lazy or IO.Lazy.
andLazy :: Monad m => m Bool -> m Bool -> m Bool Source #
Lazy monadic conjunction.
That is, when the first action returns False,
then False is immediately returned, without running the second action.
