The copy_reg module provides support for the
cPickle modules. The
copy module is likely to use this in the
future as well. It provides configuration information about object
constructors which are not classes. Such constructors may be factory
functions or class instances.
Declares object to be a valid constructor. If object is
not callable (and hence not valid as a constructor), raises

- pickle(type, function[, constructor])
Declares that function should be used as a ``reduction''
function for objects of type type; type should not a
class object. function should return either a string or a
tuple. The optional constructor parameter, if provided, is a
callable object which can be used to reconstruct the object when
called with the tuple of arguments returned by function at
pickling time. TypeError will be raised if
object is a class or constructor is not callable.
