Lisp and Scheme

Why is this shit still around? Didn't Haskell obsolete it 20 years ago?

Compare map:

 (define (map f lst)
   (let loop ((lst lst)
              (res '()))
     (if (null? lst)
       (reverse res)
       (loop (cdr lst)
             (cons (f (car lst)) res)))))

vs.

 map f []     = []
 map f (x:xs) = f x : map f xs

"map f []     = []
 map f (x:xs) = f x : map f xs
"

That map function is wrong in Haskell. The first line should be

map f _ [] = []

and not

f [] = []

Remember, map in Haskell operates on the list itself. Now get with the program and stop thinking like a C++ weenie.
