A quick experiment with Lucid 4.0's version of CLOS reveals that simple-objects have an extra overhead of 20 bytes, while ordinary structures have an overhead of 12. What else tends to be stored in objects aside from a pointer to a dispatch table? (For that matter, why might structures have 12 bytes of overhead? A 4 byte tag indicating structure + 4 byte tag indicating structure type seems more than generous to me).
