Any ideas about how to make the copy module to behave as expected.
The documentation talks about defining a "__deepcopy__" method.
Specifically, in the copy module doc
"In order for a class to define its own copy implementation, it can
define special methods __copy__() and __deepcopy__(). The former is
called to implement the shallow copy operation; no additional arguments
are passed. The latter is called to implement the deep copy operation;
it is passed one argument, the memo dictionary. If the __deepcopy__()
implementation needs to make a deep copy of a component, it should call
the deepcopy() function with the component as first argument and the
memo dictionary as second argument."
All the possible customization methods are discussed in Language
Reference 3.3. Special method names
