single: __deepcopy__() (copy protocol)

In order for a class to define its own copy implementation, it can define
special methods :meth:`__copy__` and :meth:`__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 :meth:`__deepcopy__` implementation needs
to make a deep copy of a component, it should call the :func:`deepcopy` function
with the component as first argument and the memo dictionary as second argument.
The memo dictionary should be treated as an opaque object.
special methods :meth:`~object.__copy__` and :meth:`~object.__deepcopy__`.

.. method:: object.__deepcopy__(self, memo)
:noindexentry:

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 :func:`deepcopy` function
with the component as first argument and the *memo* dictionary as second argument.
The *memo* dictionary should be treated as an opaque object.
