> I mean... you're right, you are using modules to do what you get from classes in other languages. So what?
My point is that languages that have classes also seem to need modules. Do haskell's modules address the problems that addressed by the combination of classes and modules in other languages? Does Haskell somehow avoid those problems? Is there some other mechanism?

Examples of modules can be trivial yet demonstrate why modules might be useful for large programs.
Haskell isn't object-oriented, so there aren't any little namespaces (classes) running around that themselves need to occupy a namespace (package). So modules are enough.
The Haskell wiki entry on modules is short, pretty complete, and has plenty of examples:
