---------------------------------+------------------------------------------
 There's a large space leak when deriving Generic:

 http://www.haskell.org/pipermail/cvs-ghc/2011-May/062484.html

 It is not currently derived for tuples; see changeset
 7fcfc880853fa399c9468049aeb14e6eadb9eae5 in libraries/ghc-prim.

 Test `GShow1` therefore fails at the moment.
