  	---------------------------------------
  	    Rehash the handling of SeqOp
  	---------------------------------------
  
  See the comments in the commentary (Cunning Prelude Code).
  
  * Expunge SeqOp altogether
  
  * Add GHC.Base.lazy :: a -> a
    to GHC.Base
  
  * Add GHC.Base.lazy
    to basicTypes/MkId.  The idea is that this defn will over-ride
    the info from GHC.Base.hi, thereby hiding strictness and
    unfolding
  
  * Make stranal/WorkWrap do a "manual inlining" for GHC.Base.lazy
    This happens nicely after the strictness analyser has run.
  
  * Expunge the SeqOp/ParOp magic in CorePrep
  
  * Expunge the RULE for seq in PrelRules
  
  * Change the defns of pseq/par in GHC.Conc to:
  
  	{-# INLINE pseq  #-}
         	pseq :: a -> b -> b
         	pseq  x y = x `seq` lazy y
  
         	{-# INLINE par  #-}
         	par :: a -> b -> b
         	par  x y = case (par# x) of { _ -> lazy y }
