[Haskell-cafe] Tupling functions

I would like to have tuple (f1,f2) x = (f1 x, f2 x) tuple (f1,f2,f3) x = (f1 x, f2 x, f3 x) tuple (f1,f2,f3,f4) x = (f1 x, f2 x, f3 x, f4 x) ... I'm aware of Control.Arrow and the &&& combinator, and I can use that instead, but f1 &&& f2 &&& f3 doesn't have _exactly_ the type I want. What should I do?
