That would be __copy__ or __deepcopy__, but the __getstate__ /
__setstate__ approach is often preferable.

They should, if you put them in the class of the class -- the metaclass.
>>> class mec(type):
... def __copy__(cls):
... return mec('copyof'+cls.__name__, cls.__bases__,
dict(vars(cls)))
...
>>> class foo:
... __metaclass__ = mec
...
>>> bar = copy.copy(foo)
>>> bar.__name__
'copyoffoo'
