# 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.
