What about writing a metaclass and keeping it all as portable, regular
Python code? E.g.
class MetaPickle(type):
def __call__(self, *args, **kwds):
x = type.__call__(self, *args, **kwds)
pickle.dump(x, f)
return x
class X(object):
__metaclass__ = MetaPickle
There are also ways to do it by patching the classes without changing
anything to their definition. If you need more information about these
solutions, please ask in a general Python list.
A bientot,
Armin
