That’s inavoidable if they want to learn a language which will finally be advantageous for them. If they just want another Perl or Python then there is no point in presenting Haskell to them. > there's the infamous type system, You need them to get to recognize that a powerful static type system is a very good thing (which helps solving practical problems). > there's the mystique around monads, We should just say: “warm fuzzy thing”. ;-) > there's the fear that laziness can impact performance, Hmm, tell them that performance isn’t all and that laziness helps you to write more modular programs. > the general fear that many ordinary programmers have about recursion, Then they might not be good programmers. > and so on. etc. > Giving people even the slightest reason to think that there's something > weird about opening files or printing a result is just another brick in that > wall, and it's probably the biggest brick of all. You’re right, of course. However, finally they should arrive at the point where they see that sometimes there are better tools than the IO type. > Dan Best wishes, Wolfgang _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
