This class was originally used to deal with sets being missing in
ancient versions of python, but dnspython will continue to use it
as these sets are based on lists and are thus indexable, and this
ability is widely used in dnspython applications.

There is a 'clone protocol' that subclasses of this class
should use. To make a copy, first call your super's _clone()
method, and use the object returned as the new instance. Then
make shallow copies of the attributes defined in the subclass.
This protocol allows us to write the set algorithms that
return new instances (e.g. union) once, and keep using them in
subclasses.
