[Haskell-cafe] flip1 through flip9, useful?

I have defined a bunch of functions like this: -- | Move the fourth argument to the first place rotate4 :: (a -> b -> c -> d -> e) -> (d -> a -> b -> c -> e) -- | Reverse four arguments flip4 :: (a -> b -> c -> d -> e) -> (d -> c -> b -> a -> e) I decided to upload this as a library to hackage, as I personally find it useful, especially for writing FFI bindings. It seems like I can't be the first to write a library like this though, am I missing something obvious? Is this useful or stupid? Does it exist already?
