Thanks! And posting it to Reddit has brought interesting comments too. An user that seems to have a very good knowledge in other Java functional programming API's, Haskell and mathematics posted some comments there [1]. If we come up with anything worth adding to [functor] I will invite him to bring the discussion here to the mailing list :-)
