commit b8f583928fa6cb5371a872fc73080d2002dd87d9
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Sun Sep 21 23:22:19 2014 +0200

    Export `Monoid(..)`/`Foldable(..)`/`Traversable(..)` from Prelude
    
    This finally exposes also the methods of these 3 classes in the Prelude
    in order to allow to define basic class instances w/o needing imports.
    
    This almost completes the primary goal of #9586
    
    NOTE: `fold`, `foldl'`, `foldr'`, and `toList` are not exposed yet,
          as they require upstream fixes for at least `containers` and
          `bytestring`, and are not required for defining basic instances.
