Sorry that I did not make that clear.
So in your oponion this could be a good way to learn haskell very good.

I get the feeling on your remarks that im not really to do things the 
haskell way and that is what im looking for.
I have looked at the book http://learnyouahaskell.com/chapters but I  
miss there exercises

What do you think about this one :
