While I think of a better answer this quick hack might do:

(define (copy v)
  (deserialize (serialize v))

Even in other languages you have to set each field explicitly. Theres 
probably some way of iterating through the fields in a class with a 
macro or something to make it easier. What do you mean by pointers? Boxes?
