The proposal is that the following functions (<$) :: Functor f => a -> f b -> f a (*>) :: Applicative f => f a -> f b -> f b (<*) :: Applicative f => f a -> f b -> f a some :: Alternative f => f a -> f [a] many :: Alternative f => f a -> f [a] are moved into the corresponding classes, with the existing implementations as default definitions. This gives people creating instances the option of defining specialized implementations of these functions, though they should be equivalent to the default definitions. Although (<$) 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. Deadline: 20th July 2009.
