i recommend you to read http://haskell.org/haskellwiki/OOP_vs_type_classes
first and then look into http://haskell.org/haskellwiki/Library/Streams
 - it's a good example of extensible library written using type
 classes. later i've used this approach to write extensible library in
 C++ using templates (not classes)
