commit 6ecc0777736366d3a41db167aa56817c2cf512d2
Author: Edward Kmett <ekmett at gmail.com>
Date:   Tue Oct 8 21:22:14 2013 -0400

    Rename (:=:) to (:~:) and add Data.Type.Coercion
    
    Bikeshed color chosen by core libraries committee
    
    Knock-on effects:
    
    * Made the instances for Read, Enum, Data and Bounded for (:~:) more robust
    * Renamed Data.Type.Equality.coerce to subst. It collided with GHC.Prim.coerce from Coercible.
