4438	"Rename and register the ""PArr"" language extension when it is judged to be ready"	duncan	benl	"Language extensions used in distributed packages need to be registered in `Language.Haskell.Extension` (which currently lives in the Cabal lib).

When the DPH hackers think that the `PArr` extension is ready for public consumption then they should register it. It will need to be renamed to something more descriptive, see the `Language.Haskell.Extension` module for examples. The style is to use full words. Perhaps `ParallelArrays` would be an appropriate choice.

Currently the `PArr` extension is the only GHC extension that is deliberately not registered (there are others that are accidentally not registered). It is listed as an exception in the testsuite test that checks for GHC extensions that are accidentally not registered.
