3. mkJustExpr :: Type -> CoreExpr -> CoreExpr

   ghc-lib-parser	GHC.Core.Make

   Makes a Just from a value of the specified type

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

   ghc-lib-parser	GHC.Core.TyCon.Env

   No documentation available.

5. expectJust :: HasDebugCallStack => String -> Maybe a -> a

   ghc-lib-parser	GHC.Data.Maybe

   No documentation available.

6. firstJust :: Maybe a -> Maybe a -> Maybe a

   ghc-lib-parser	GHC.Data.Maybe

   No documentation available.

7. 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.

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

   ghc-lib-parser	GHC.Data.Maybe

   Takes computations returnings Maybes; tries each one in order. The first one to return a Just wins. Returns Nothing if all computations return Nothing.

9. whenIsJust :: Monad m => Maybe a -> (a -> m ()) -> m ()

   ghc-lib-parser	GHC.Data.Maybe

   No documentation available.

10. adjust :: (a -> a) -> Key -> Word64Map a -> Word64Map a

    ghc-lib-parser	GHC.Data.Word64Map.Internal

    Adjust a value at a specific key. When the key is not a member of the map, the original map is returned.

    adjust ("new " ++) 5 (fromList [(5,"a"), (3,"b")]) == fromList [(3, "b"), (5, "new a")]
    adjust ("new " ++) 7 (fromList [(5,"a"), (3,"b")]) == fromList [(3, "b"), (5, "a")]
    adjust ("new " ++) 7 empty                         == empty
