Details:

(lambda (xs) xs)) and (lambda xs xs) wrongfully expand to the same code:


(equal?
  (expand '(lambda  xs  xs))
  (expand '(lambda (xs) xs))) ; => #t


This is obviously incorrect since there is a difference between the two:


(equal?
  ((lambda  xs  xs) 'arg)
  ((lambda (xs) xs) 'arg)) ; => #f
