Comment (by yoeight):

 Thanks for your advices !

 I made Pred a type synonym of TH.Type.

 Impacted files sum up:

 {{{
 dph-lifted-copy/Data/Array/Parallel/Lifted/TH/Repr.hs

 compiler/hsSyn/Convert.lhs
 compiler/typecheck/TcSplice.lhs

 Language/Haskell/TH.hs
 Language/Haskell/TH/Lib.hs
 Language/Haskell/TH/Ppr.hs
 Language/Haskell/TH/Syntax.hs
 }}}

 I have also made a test case based on description snippet
