Hello Geniuses!
I am beginner in haskell and going through learn you a haskell.
In recursion chapter, there is an implementation of take function. I am trying to implement it another way but keep getting compiler error "Not in scope: 'as'"
Here is the code:
take' :: Int -> [a] -> [a]
take' _ [] = []
take' x _
| x _ <= 0 = []
| otherwise x (a:as) = a : take' (x-1) as
Can someone tell me what is wrong with this program?

Here is the code:
take'' :: Int -> [a] -> [a]
take'' _ [] = []
take'' x (a:as)
take'' :: Int -> [a] -> [a]
take'' _ [] = []
| x <= 0 = []
| otherwise = take' (x-1) as
