[Python-ideas] Put default setstate and getstate on object for use in coöperative inheritance.

When implementing getstate in coöoerative inheritance, the typical thing to do is to call super to get dictionary and add the appropriate entries. Setstate is similar: you extract what you need out of the dictionary and call super with the remaining entries. Unfortunately, object does not have a default implementation, so you need a base class like so: class DefaultSetstateAndGetstate: """ Define default getstate and setstate for use in coöperative inheritance. """ def __getstate__(self): return self.__dict__.copy() def __setstate__(self, state): self.__dict__.update(state) I suggest that this be added to object. Best, Neil
