As I understand it,  mtl  is to be replaced by  transformers  and one of
the  monads-*  packages in the future, though there is no clear
recommendation yet. See also

  http://thread.gmane.org/gmane.comp.lang.haskell.libraries/12229/

Also, it seems that there is currently no community preference choice
for either type families or functional dependencies.


Personally, I didn't want to think about this and simply chose  mtl .
But if you like type families a lot, I see no problem with going ahead
and using  transformers + monads-tf .
