1. districtList :: [(Text, StateCode)]

   state-codes	Data.StateCodes

   List of districts sorted by alphabetical order, with state code this is ready to be used in a yesod selectField, for example

2. outlyingAreasList :: [(Text, StateCode)]

   state-codes	Data.StateCodes

   List of outlying areas sorted by alphabetical order, with state code this is ready to be used in a yesod selectField, for example

3. stateList :: [(Text, StateCode)]

   state-codes	Data.StateCodes

   List of states sorted by alphabetical order, with state code this is ready to be used in a yesod selectField, for example

4. fromList :: Ord k => [(Bound k, v)] -> v -> SF k v

   step-function	Data.Function.Step

   Create function from list of cases and default value.

   >>> let f = fromList [(Open 1,2),(Closed 3,4),(Open 4,5)] 6
   
   >>> putSF f
   \x -> if
   | x <  1    -> 2
   | x <= 3    -> 4
   | x <  4    -> 5
   | otherwise -> 6
   

   >>> map (f !) [0..10]
   [2,4,4,4,6,6,6,6,6,6,6]
   

5. fromList :: Ord k => [(k, v)] -> v -> SF k v

   step-function	Data.Function.Step.Discrete.Closed

   Create function from list of cases and default value.

   >>> let f = fromList [(1,2),(3,4)] 5
   
   >>> putSF f
   \x -> if
   | x <= 1    -> 2
   | x <= 3    -> 4
   | otherwise -> 5
   

   >>> map (f !) [0..10]
   [2,2,4,4,5,5,5,5,5,5,5]
   

6. fromList :: Ord k => [(k, v)] -> v -> SF k v

   step-function	Data.Function.Step.Discrete.Open

   Create function from list of cases and default value.

   >>> putSF $ fromList [(1,2),(3,4)] 5
   \x -> if
   | x < 1     -> 2
   | x < 3     -> 4
   | otherwise -> 5
   

   >>> map (fromList [(1,2),(3,4)] 5 !) [0..10]
   [2,4,4,5,5,5,5,5,5,5,5]
   

7. fromList :: Unbox a => [a] -> Array a

   streamly	Streamly.Data.Array.Foreign

   Create an Array from a list. The list must be of finite size.

8. fromListN :: Unbox a => Int -> [a] -> Array a

   streamly	Streamly.Data.Array.Foreign

   Create an Array from the first N elements of a list. The array is allocated to size N, if the list terminates before N elements then the array may hold less than N elements.

9. toList :: Unbox a => Array a -> [a]

   streamly	Streamly.Data.Array.Foreign

   Convert an Array into a list.

10. class IsList l

    streamly	Streamly.Data.Stream.MkType

    The IsList class and its methods are intended to be used in conjunction with the OverloadedLists extension.
