Re: [Haskell-cafe] Type unions

Try making a type class for the functions. That will allow you both varargs and unions. Have a look at Text.Printf.

Thank you -- looking at Printf was very helpful. My syntax is much happier as a result. I also see now that I am approaching the problem from the wrong direction -- that by writing a whole slew of functions whose behavior depends arbitrarily upon their argument type, I would need to code the desired behavior for each function and each argument type; getting hung up on making the syntax manageable hid this realization from me. The solution is for me to try much harder to extract common behavior across argument types and only code special cases when truly necessary. Eric
