Re: [Haskell-cafe] creating graphics the functional way

Is it possible to write functions with an arbitrary number of arguments? Would be nice if the average function would accept any number of pixel values.

I think it's possible in some sense, because the Haskell interpretation of printf() works in the normal way. But there might be a bit of voodoo involved. Easier is to just pass a list of arguments to calculate over. (The following is neither correct nor fast...)

avg xs = sum xs `div` length xs
