1. getIdFromTrivialExpr_maybe :: CoreExpr -> Maybe Id

   ghc	GHC.Core.Utils

   No documentation available.

2. normSplitTyConApp_maybe :: FamInstEnvs -> Type -> Maybe (TyCon, [Type], Coercion)

   ghc	GHC.Core.Utils

   If normSplitTyConApp_maybe _ ty = Just (tc, tys, co) then ty |> co = tc tys. It's splitTyConApp_maybe, but looks through coercions via topNormaliseType_maybe. Hence the "norm" prefix.

3. catBagMaybes :: Bag (Maybe a) -> Bag a

   ghc	GHC.Data.Bag

   No documentation available.

4. headMaybe :: Bag a -> Maybe a

   ghc	GHC.Data.Bag

   No documentation available.

5. mapMaybeBag :: (a -> Maybe b) -> Bag a -> Bag b

   ghc	GHC.Data.Bag

   No documentation available.

6. mapMaybeBagM :: Monad m => (a -> m (Maybe b)) -> Bag a -> m (Bag b)

   ghc	GHC.Data.Bag

   No documentation available.

7. mapMaybeFsEnv :: (elt1 -> Maybe elt2) -> FastStringEnv elt1 -> FastStringEnv elt2

   ghc	GHC.Data.FastString.Env

   No documentation available.

8. assocMaybe :: Eq a => Assoc a b -> a -> Maybe b

   ghc	GHC.Data.List.SetOps

   Lookup key, fail gracefully using Nothing if not found.

9. liftMaybeT :: Monad m => m a -> MaybeT m a

   ghc	GHC.Data.Maybe

   No documentation available.

10. rightToMaybe :: Either a b -> Maybe b

    ghc	GHC.Data.Maybe

    No documentation available.
