Class::Std's inside out objects are wonderful, but all the common
serialisation packages assume that because they can see inside them, they
can successfully serialise your object. Wrong! Because all they serialise
is the ID, you may suffer data loss without realising.

Acme::Class::Std shows those pesky serialise modules just who is boss. They
can go peeking and prodding, but they will get their fingers burnt:
