Anyway, bool is the natural parameter order in Haskell. I'll make more explicit what others have already said, with this analogy:

maybe (if it fails) (if it succeeds) (input data) either (if it fails) (if it succeeds) (input data)

foldl (if it's null) (if it's not null) (input data) foldr (if it's null) (if it's not null) (input data)

Unfortunately, it is the other way round: foldl (if it's not null) (if it's null) (input data) foldr (if it's not null) (if it's null) (input data)
