(** Operations on objects *)

val copy : (< .. > as 'a) -> 'a
(** [Oo.copy o] returns a copy of object [o], that is a fresh
   object with the same methods and instance variables as [o]. *)

external id : < .. > -> int = "%field1"
(** Return an integer identifying this object, unique for
    the current execution of the program. The generic comparison
    and hashing functions are based on this integer. When an object
    is obtained by unmarshaling, the id is refreshed, and thus
    different from the original object. As a consequence, the internal
    invariants of data structures such as hash table or sets containing
    objects are broken after unmarshaling the data structures.
