(lambda lists (apply map list lists))

If zip is passed N lists, it returns a list as long as the shortest of these lists, each element of which is an N-element list comprised of the corresponding elements from the parameter lists.

(zip '(one two three) 
     '(1 2 3)
     '(odd even odd even odd even odd even))
    => ((one 1 odd) (two 2 even) (three 3 odd))
 
(zip '(1 2 3)) => ((1) (2) (3))

At least one of the argument lists must be finite:

(zip '(3 1 4 1) (circular-list #f #t)) 
    => ((3 #f) (1 #t) (4 #f) (1 #t))
