As was previously noted they are supposed to be replaced by type families,

Hi Eduard

Currently this seems a more like a rumour than a fact - from [1] Type Families and Fun Deps are equivalently expressive which seems a worthwhile point to restate. From [2] the Haskell prime committee want one or the other but not both, and will resolve matters sometime in the future.
