  9. data UnliftedMutVar# s (a :: UnliftedType)

    primitive-unlifted Data.Primitive.Unlifted.MutVar.Primops

    An UnliftedMutVar# behaves like a single-element mutable array.

  10. atomicSwapUnliftedMutVar# :: forall s (a :: UnliftedType) . UnliftedMutVar# s a -> a -> State# s -> (# State# s, a #)

    primitive-unlifted Data.Primitive.Unlifted.MutVar.Primops

    Atomically replace the value in an UnliftedMutVar# with the given one, returning the old value. Implementation note: this really should be a GHC primop, because it is supported very efficiently in hardware, but unfortunately it's not (yet), so we implement it as a CAS loop.
