-- BIG UGLY HACK: The desugarer special cases this module. Despite the uses of '-XParallelArrays',
-- the desugarer does not load 'Data.Array.Parallel' into its global state. (Hence,
-- the present module may not use any other piece of '-XParallelArray' syntax.)
--
-- This will be cleaned up when we change the internal represention of '[::]' to not
-- rely on a wired-in type constructor.

import GHC.Base
-- Representation of parallel arrays
--
-- Vanilla representation of parallel Haskell based on standard GHC arrays that is used if the
-- vectorised is /not/ used.

-- NB: This definition *must* be kept in sync with `TysWiredIn.parrTyCon'!

data [::] e = PArr !Int (Array# e)
type PArr = [::] -- this synonym is to get access to '[::]' without using the special syntax
