1. last :: HasCallStack => WindowsString -> WindowsChar

   os-string	System.OsString.Windows

   O(1) Extract the last element of a OsString, which must be finite and non-empty. An exception will be thrown in the case of an empty OsString. This is a partial function, consider using unsnoc instead.

2. last :: IsNonEmpty f a a "last" => f a -> a

   relude	Relude.List.NonEmpty

   O(n). Extracts the last element of a NonEmpty list. Actual type of this function is the following:

   last :: NonEmpty a -> a
   

   but it was given a more complex type to provide friendlier compile time errors.

   >>> last ('a' :| "bcde")
   'e'
   
   >>> last [0..5 :: Int]
   ...
   ... 'last' works with 'NonEmpty', not ordinary lists.
   Possible fix:
   Replace: [Int]
   With:    NonEmpty Int
   ...
   However, you can use 'last' with the ordinary lists.
   Apply 'viaNonEmpty' function from relude:
   viaNonEmpty last (yourList)
   Note, that this will return 'Maybe Int'
   therefore it is a safe function unlike 'last' from the standard Prelude
   ...
   
   >>> last (Just 'a')
   ...
   ... 'last' works with 'NonEmpty Char' lists
   But given: Maybe Char
   ...
   

3. last :: HasCallStack => [a] -> a

   relude	Relude.Unsafe

   Extract the last element of a list, which must be finite and non-empty. WARNING: This function is partial. Consider using unsnoc instead.

   Examples

   >>> last [1, 2, 3]
   3
   

   >>> last [1..]
   * Hangs forever *
   

   >>> last []
   *** Exception: Prelude.last: empty list
   

4. last :: Monad m => Stream (Of a) m r -> m (Of (Maybe a) r)

   streaming	Streaming.Prelude

   No documentation available.

5. last :: YiString -> Maybe Char

   yi-rope	Yi.Rope

   Take the last character of the underlying string if possible.

6. last :: NonEmpty a -> a

   base-compat-batteries	Data.List.NonEmpty.Compat

   Extract the last element of the stream.

7. last :: forall (v :: Type -> Type) (n :: Natural) a . Vector v a => Vector v (n + 1) a -> a

   vector-sized	Data.Vector.Generic.Sized

   O(1) Yield the last element of a non-empty vector.

8. last :: forall (n :: Natural) a . Prim a => Vector (n + 1) a -> a

   vector-sized	Data.Vector.Primitive.Sized

   O(1) Yield the last element of a non-empty vector.

9. last :: forall (n :: Natural) a . Vector (n + 1) a -> a

   vector-sized	Data.Vector.Sized

   O(1) Yield the last element of a non-empty vector.

10. last :: forall (n :: Natural) a . Storable a => Vector (n + 1) a -> a

    vector-sized	Data.Vector.Storable.Sized

    O(1) Yield the last element of a non-empty vector.
