1. appendList :: NonEmpty a -> [a] -> NonEmpty a

   base	Data.List.NonEmpty

   Attach a list at the end of a NonEmpty.

   >>> appendList (1 :| [2,3]) []
   1 :| [2,3]
   

   >>> appendList (1 :| [2,3]) [4,5]
   1 :| [2,3,4,5]
   

2. fromList :: HasCallStack => [a] -> NonEmpty a

   base	Data.List.NonEmpty

   Converts a normal list to a NonEmpty stream. Raises an error if given an empty list.

3. prependList :: [a] -> NonEmpty a -> NonEmpty a

   base	Data.List.NonEmpty

   Attach a list at the beginning of a NonEmpty.

   >>> prependList [] (1 :| [2,3])
   1 :| [2,3]
   

   >>> prependList [negate 1, 0] (1 :| [2, 3])
   -1 :| [0,1,2,3]
   

4. toList :: NonEmpty a -> [a]

   base	Data.List.NonEmpty

   Convert a stream to a normal list efficiently.

5. primMapListBounded :: BoundedPrim a -> [a] -> Builder

   bytestring	Data.ByteString.Builder.Prim

   Create a Builder that encodes a list of values consecutively using a BoundedPrim for each element. This function is more efficient than

   mconcat . map (primBounded w)
   

   or

   foldMap (primBounded w)
   

   because it moves several variables out of the inner loop.

6. primMapListFixed :: FixedPrim a -> [a] -> Builder

   bytestring	Data.ByteString.Builder.Prim

   Encode a list of values from left-to-right with a FixedPrim.

7. toList :: Array -> Int -> Int -> [Word8]

   text	Data.Text.Array

   Convert an immutable array to a list.

8. streamList :: [a] -> Stream a

   text	Data.Text.Internal.Fusion.Common

   O(n) Convert a list into a Stream. Properties

   unstream . streamList = pack
   

9. unstreamList :: Stream a -> [a]

   text	Data.Text.Internal.Fusion.Common

   O(n) Convert a Stream into a list. Properties

   unstreamList . stream = unpack
   

10. fromAscList :: [(Key, a)] -> IntMap a

    containers	Data.IntMap.Internal

    Build a map from a list of key/value pairs where the keys are in ascending order.

    fromAscList [(3,"b"), (5,"a")]          == fromList [(3, "b"), (5, "a")]
    fromAscList [(3,"b"), (5,"a"), (5,"b")] == fromList [(3, "b"), (5, "b")]
