Repository : ssh://darcs.haskell.org//srv/darcs/packages/base

Branch 'ghc-7.2' now includes:

     2ceacbc... Move the munzip function in the Zip type class;
     91f37c8... small tweaks to docs
     122140d... export unsafeDupablePerformIO
     f1732ae... Implement unsafeLocalState by unsafeDupablePerformIO, not unsafePerformIO.  The latter is more efficient, and will work correctly for clients that are using unsafeLocalState for its documented uses.
     c80c5cb... give instances of Ord for TyCon and TypeRep
     77c2f49... DEPRECATE typeRepKey
