1. fromListMutableN :: forall (arr :: Type -> Type) a m . (Contiguous arr, Element arr a, PrimMonad m) => Int -> [a] -> m (Mutable arr (PrimState m) a)

   contiguous	Data.Primitive.Contiguous

   Given an Int that is representative of the length of the list, convert the list into a mutable array of the given length. Note: calls error if the given length is incorrect.

2. fromListN :: (Contiguous arr, Element arr a) => Int -> [a] -> arr a

   contiguous	Data.Primitive.Contiguous

   Given an Int that is representative of the length of the list, convert the list into a mutable array of the given length. Note: calls error if the given length is incorrect.

3. fromListWithKey :: Ord k => (k -> v -> v -> v) -> [(k, v)] -> Map k v

   dhall	Dhall.Map

   Create a Map from a list of key-value pairs with a combining function.

   >>> fromListWithKey (\k v1 v2 -> k ++ v1 ++ v2) [("B","v1"),("A","v2"),("B","v3")]
   fromList [("B","Bv3v1"),("A","v2")]
   

4. fromListN :: IsList l => Int -> [Item l] -> l

   foundation	Foundation

   The fromListN function takes the input list's length and potentially uses it to construct the structure l more efficiently compared to fromList. If the given number does not equal to the input list's length the behaviour of fromListN is not specified.

   fromListN (length xs) xs == fromList xs
   

5. fromLists :: Context a => [[a]] -> Matrix a

   matrices	Data.Matrix

   O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix

6. fromLists :: forall m (v :: Type -> Type) a . Matrix m v a => [[a]] -> m v a

   matrices	Data.Matrix.Class

   O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix

7. fromLists :: forall m (v :: Type -> Type) a . Matrix m v a => [[a]] -> m v a

   matrices	Data.Matrix.Generic

   O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix

8. fromLists :: forall m (v :: Type -> Type) a . Matrix m v a => [[a]] -> m v a

   matrices	Data.Matrix.Sparse.Generic

   O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix

9. fromLists :: Context a => [[a]] -> Matrix a

   matrices	Data.Matrix.Storable

   O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix

10. fromLists :: Context a => [[a]] -> Matrix a

    matrices	Data.Matrix.Unboxed

    O(m*n) Create matrix from list of lists, it doesn't check if the list of list is a valid matrix
