I belive that the first source is Gofer documentation for 2.30 version. I don't know about a tutorial. There is a presentation in the paper "Imperative Funcional Programming" from Peyton Jones and Wadler, which if available via WWW from: http://www.dcs.gla.ac.uk/~simonpj/ If you find a better stuff, please, let me know. >I have recently started using gofer 2.30 which provides monadic IO but >unfortunately I don't quite know how to use it. > >May I know some tutorial sources for monadic IO?
