but, as I've understood, it is required to mark as "weak" every reference to the object?

No, the typical use would be to have only %already_created_objects contain weak references. Then normal object life-time control would take place and when an object is no longer referenced other than in %already_created_objects, that object would be destroyed and the value in %already_created_objects would transform into undef.

If there is some reason you want to destroy the object while there are still live references to it besides %already_created_objects, then you should give more information to justify that unusual requirement.
