(*) Find the last element of a list.

myLast :: [a] -> a
myLast [x] = x
myLast (_:xs) = myLast xs

myLast' = foldr1 (const id)

-- Prelude> const 1 2
-- 1
-- Prelude> (flip const) 1 2
-- 2
myLast'' = foldr1 (flip const)

myLast''' = head . reverse

myLast'''' = foldl1 (curry snd)

myLast''''' [] = error "No end for empty lists!"  
myLast''''' x = x !! (length x -1)

The Prelude also provides the function last.
