I am porting a C++ program to Haskell. My current task is to take a class hierarchy and produce something equivalent in Haskell
Did you define that task for yourself, or is someone else asking you to do it? There really isn't anything equivalent in Haskell. Typeclasses in Haskell are not the same as classes in C++. You may or may not need typeclasses in your Haskell program (probably not), but whether or not you need them and how you will structure them if you do has little or nothing to do with what the class hierarchy looks like in C++. The only way to do a good job of porting a program from C++ to Haskell is to begin with a description of what the program does and what its requirements are. Regards, Yitz
