30 val id : < .. > -> int
31
32 Return an integer identifying this object, unique for the current exe‐
33 cution of the program. The generic comparison and hashing functions are
34 based on this integer. When an object is obtained by unmarshaling, the
35 id is refreshed, and thus different from the original object. As a con‐
36 sequence, the internal invariants of data structures such as hash table
37 or sets containing objects are broken after unmarshaling the data
38 structures.
