1. foldl1Elems :: (a -> a -> a) -> Array i a -> a

   base	GHC.Arr

   A left fold over the elements with no starting value

2. foldlElems :: (b -> a -> b) -> b -> Array i a -> b

   base	GHC.Arr

   A left fold over the elements

3. foldlElems' :: (b -> a -> b) -> b -> Array i a -> b

   base	GHC.Arr

   A strict left fold over the elements

4. foldl' :: forall a b . (b -> a -> b) -> b -> [a] -> b

   base	GHC.List

   A strict version of foldl.

5. foldl1 :: HasCallStack => (a -> a -> a) -> [a] -> a

   base	GHC.List

   foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty lists. Note that unlike foldl, the accumulated value must be of the same type as the list elements.

   >>> foldl1 (+) [1..4]
   10
   
   >>> foldl1 (+) []
   *** Exception: Prelude.foldl1: empty list
   
   >>> foldl1 (-) [1..4]
   -8
   
   >>> foldl1 (&&) [True, False, True, True]
   False
   
   >>> foldl1 (||) [False, False, True, True]
   True
   
   >>> foldl1 (+) [1..]
   * Hangs forever *
   

6. foldl1' :: HasCallStack => (a -> a -> a) -> [a] -> a

   base	GHC.List

   A strict version of foldl1.

7. foldl' :: (a -> Word8 -> a) -> a -> ByteString -> a

   bytestring	Data.ByteString

   foldl' is like foldl, but strict in the accumulator.

8. foldl1 :: HasCallStack => (Word8 -> Word8 -> Word8) -> ByteString -> Word8

   bytestring	Data.ByteString

   foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty ByteStrings. An exception will be thrown in the case of an empty ByteString.

9. foldl1' :: HasCallStack => (Word8 -> Word8 -> Word8) -> ByteString -> Word8

   bytestring	Data.ByteString

   foldl1' is like foldl1, but strict in the accumulator. An exception will be thrown in the case of an empty ByteString.

10. foldl' :: (a -> Char -> a) -> a -> ByteString -> a

    bytestring	Data.ByteString.Char8

    foldl' is like foldl, but strict in the accumulator.
