1. suchThatMaybe :: Gen a -> (a -> Bool) -> Gen (Maybe a)

   QuickCheck	Test.QuickCheck

   Tries to generate a value that satisfies a predicate. If it fails to do so after enough attempts, returns Nothing.

2. suchThatMaybe :: Gen a -> (a -> Bool) -> Gen (Maybe a)

   QuickCheck	Test.QuickCheck.Gen

   Tries to generate a value that satisfies a predicate. If it fails to do so after enough attempts, returns Nothing.

3. mapMaybe :: (a -> Maybe b) -> KeyMap a -> KeyMap b

   aeson	Data.Aeson.KeyMap

   Map values and collect the Just results.

4. mapMaybeWithKey :: (Key -> v -> Maybe u) -> KeyMap v -> KeyMap u
