`uuid` module

Random (version 4) UUIDs. Useful for request IDs, session IDs, and database primary keys when you don't want to round-trip through the DB to mint one.

import "uuid" as uuid;

var id = uuid.v4();
print(id);                      // 550e8400-e29b-41d4-a716-446655440000
print(uuid.is_valid(id));       // true
print(uuid.is_v4(id));          // true
