How to redefine object so that all user- objects have the necessary capabilities?

[AlekseyPython]

When I used the pickle library, it turned out that it does not save the current values ​​of the class members (after recovery pickle fills them with the original values). Pickle save only current values of instance variables. Therefore, I wrote a class 'AbstractSavingObject', which implements saving, including the current values ​​of class variables. Now I want to give this opportunity to all my classes (for the ability to save in a dump all objects when an exception occurs) and do not want to write inheritance from 'AbstractSavingObject' everywhere.

How to do this?
