Starting with IO in Haskell is like starting LaTeX with rotating text and making it colorful. Indeed IO _is_ complicated regardless of whether it is modelled by Monads in Haskell or differently in other languages. Beginners should start with non-monadic functions in order to later avoid IO in their functions whereever possible. There are a lot of non-IO applications a beginner can start with, such as using Hugs or GHCi as a programmable calculator. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
