[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?
