1. mapUrls :: UrlMap -> Application

   wai-extra	Network.Wai.UrlMap

   No documentation available.

2. mapException :: (Exception e1, Exception e2) => (e1 -> e2) -> a -> a

   lifted-base	Control.Exception.Lifted

   This function maps one exception into another as proposed in the paper "A semantics for imprecise exceptions".

3. mapItems :: (Item a -> Item b) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Extension.Spec

   No documentation available.

4. mapItems :: (Item () -> Item ()) -> [SpecTree] -> [SpecTree]

   hspec-core	Test.Hspec.Core.Extension.Tree

   No documentation available.

5. mapSubject :: (b -> a) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Hooks

   Modify the subject under test. Note that this resembles a contravariant functor on the first type parameter of SpecM. This is because the subject is passed inwards, as an argument to the spec item.

6. mapSpecForest :: ([SpecTree a] -> [SpecTree b]) -> SpecM a r -> SpecM b r

   hspec-core	Test.Hspec.Core.Spec

   No documentation available.

7. mapSpecItem :: (ActionWith a -> ActionWith b) -> (Item a -> Item b) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Spec

   Deprecated: Use mapSpecItem_ instead.

8. mapSpecItem_ :: (Item a -> Item b) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Spec

   No documentation available.

9. mapFoldable :: forall (m :: Type -> Type) t a b r . (Functor m, Foldable t) => (a -> t b) -> Pipe a b m r

   pipes	Pipes.Prelude

   Apply a function to all values flowing downstream, and forward each element of the result.

10. mapM :: Monad m => (a -> m b) -> Pipe a b m r

    pipes	Pipes.Prelude

    Apply a monadic function to all values flowing downstream

    mapM return = cat
    
    mapM (f >=> g) = mapM f >-> mapM g
