Alfonso, you may be interested in reading the following pages where i put
some examples of passing functions in the cases where OOP programmers use
classes. after all, OOP class is just data+functions bundled together,
while in Haskell these are separate concepts

http://haskell.org/haskellwiki/OOP_vs_type_classes
http://haskell.org/haskellwiki/IO_inside (look at "Example: a list of IO
actions" and next chapters)
