[Haskell-cafe] complete documentation like the one from Java or C++

Hellow, can you tell me where I can find a more explicit documentation for the Haskell library and maybe for some of the extentions. GHC comes with something but is not as I want. I would like them to tell me for a function what it does not only what arguments it takes and what it returnes. And maybe some hints about how it works if not some examples. I would like something that approch the one from Java or .NET or MSDN. thank you for your time and understanding
