DefaultOrderedDict save it to a file with pickle

[guardeivid]

Hi,
Excellent work.
I am trying to save the dictionary open with mappyfile in a file, using pickle, but I get the following error:

mapy = mappyfile.open(path)
pickle.dump(mapy, open('file', 'wb'))

_pickle.PicklingError: fifth element of the tuple returned by __reduce__ must be an iterator, not odict_items.

I understand that this is the function::

    def __reduce__(self):
        if self.default_factory is None:
            args = tuple()
        else:
            args = self.default_factory,
        return type(self), args, None, None, self.items()

Is it possible to return an iterator instead of self.items()?

Thanks!

@guardeivid - glad you like the library.
I added a pickle test but wasn't able to recreate the issue. Would you be able to provide a minimal Mapfile snippet that causes this?

Ok the pickle test works in Python2 and not Python3, I'll add a fix for this. Thanks for reporting.

Yes, the error was in Python3. Great now it works correctly,

Many Thanks!
