If you are to describe a system, which consists of several subsystems, how do you approach the problem? What types, classes, functions whatever do you introduce?
I guess it is a common problem, is there a general method? Just to describe, not to solve (though if the description implies the solution then it is wonderful).
Obviously this is not just a haskell-specific problem, but I think there might be people who are aware of the best current solution (category theory?).
In general I view the subsystems as completely separate, as far as possible. Then I write a library for each of them, combining them later in a program. Also I try to find a design pattern for the general problem at hand, although I almost always end up using FRP. Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/
