Re-export UnliftedRep and UnliftedType from GHC.Exts
We usually want to avoid users having to import GHC.Prim
or GHC.Types
, so I think it makes sense to re-export UnliftedType
and UnliftedRep
from GHC.Exts
.
I'm tagging this as a backport for GHC 9.2
, as that's the version which introduces BoxedRep
.
