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

[Bas van Dijk]

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 ()
