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

[Bas van Dijk]

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
