Comment:
Data Parallel Haskell code must be compiled with '-fvectorise'. If you do
that for this example, the vectoriser will complain that it cannot
vectorise `String`. As explained on
http://haskell.org/haskellwiki/GHC/Data_Parallel_Haskell only types from
the mock Prelude `Data.Array.Parallel.Prelude.*` are being support at the
moment.
(Besides, DPH isn't in a usable state in 7.0.x. You need to use 7.2.x,
which has limited support for DPH.)
