[Haskell-cafe] different arities

These two functions have the same type. Is this behaviour intended? (Can functions of the same type have different arities?) ------------------------------------------- data Fun = Increment | Square fun:: Fun -> Int -> Int fun Increment n = n+1 fun Square = (\n -> n*n) ------------------------------------------- Error message in HUGS: ERROR "arity.hs":17 - Equations give different arities for "fun GHC: arity.hs:3: Varying number of arguments for function `fun' /Regards Henning
