[Pharo-users] Passed by references and by value

Hi, In PBE says that ordinary objects' ivars are passed by references and small integers are passed by value. Is there a way to know if a class is passed by reference or by value? Only small integers are passed as value? Thanks in advance Nacho ----- Nacho Smalltalker apprentice.
