4. mkJustExpr :: Type -> CoreExpr -> CoreExpr

   ghc-lib-parser	GHC.Core.Make

   Makes a Just from a value of the specified type

5. adjustDTyConEnv :: (a -> a) -> DTyConEnv a -> TyCon -> DTyConEnv a

8. firstJusts :: Foldable f => f (Maybe a) -> Maybe a

   ghc-lib-parser	GHC.Data.Maybe

   Takes a list of Maybes and returns the first Just if there is one, or Nothing otherwise.

9. firstJustsM :: (Monad m, Foldable f) => f (m (Maybe a)) -> m (Maybe a)
