Of course, one of the most common ways of structuring large programs is to use a module system. But Haskell's module system is quite simple and conventional. In essence, it just provides mechanisms for namespace control, and there is not even any standard notion of an interface or signature. It does have one interesting feature in its support for mutually recursive modules, which have proved to be quite useful for programmers (but quite a headache for some Haskell implementors!). Davide Ancona will say more about such things later in this session. So I don't think it would be interesting to say much more about Haskell's module system in this talk. Instead, we should ask what features make program structuring in Haskell any different from program structuring in other languages? |
