Although (<$) is now a method of the Functor class, it is hidden in the
re-export by the Prelude, Control.Monad and Monad. The new module
Data.Functor exposes the full class, plus the function (<$>). These are
also re-exported by Control.Applicative.

Could we come up with some policy on what goes in Control.* versus Data.*? As we add more and more modules that fits in both categories it's becoming increasingly hard to remember what lives where. Using both Data and Control gives import lists an ugly asymmetry:

import Control.Applicative
import Data.Functor
import Control.Monad

Cheers,
