Re: Proposal: alpha-rename the type signatures of foldl, foldl', and scanl to be consistent with foldr and scanr

Ian, I think you missed some fixes in Data.Foldable from the original patch: foldl :: (a -> b -> a) -> a -> t b -> a to: foldl :: (b -> a -> b) -> b -> t a -> b foldl' :: (a -> b -> a) -> a -> t b -> a to: foldl' :: (b -> a -> b) -> b -> t a -> b foldlM :: (Foldable t, Monad m) => (a -> b -> m a) -> a -> t b -> m a to: foldlM :: (Foldable t, Monad m) => (b -> a -> m b) -> b -> t a -> m b On 9 November 2012 10:29, Bas van Dijk wrote:

Hi,

We should make this same change in Control.Monad:

foldM :: Monad m => (a -> b -> m a) -> a -> [b] -> m a to: foldM :: Monad m => (b -> a -> m b) -> b -> [a] -> m b

foldM_ :: Monad m => (a -> b -> m a) -> a -> [b] -> m () to: foldM_ :: Monad m => (b -> a -> m b) -> b -> [a] -> m ()

I've attached a patch.

I've applied the patch, and also the other agreed changes.

Thanks Ian
