You mean a single argument list.

In any case, his tup is more like a curried xmap.
I think a plain exchanged map should look like this:

(define (xmap funcs args)
  (map (lambda (func)
         (apply func args))
       funcs))

(xmap (list first third second) '((a b c d e)))
=> (a c b)

The second argument to this xmap is a doubled list because it's a list  
of arguments, containing a single argument which is itself a list.
