One other thing: using refaddr is not safe when using fork() (on windows) or threads (on any system) since the refaddr changes over a CLONE. Object::InsideOut seems to deal with this issue.
But at what cost. Object::InsideOut has a huge overhead: Over 90% of the run time of the test script of the poster is spent generating a unique id for the objects. Madness.
