So, I don't think this would justify breaking backward-compatibility. As far as I know, the removal of the old-style classes does not break old pickle streams, since the code of classes is not pickled but referenced. > * Remove the backwards compatible stuff from the documentation > only.

In fact, some sections are outright wrong about how the current module works. If I get some free time (which is unlikely, right now), I will update the documentation. > * Leave the old code in but generate warnings when old pickle > mechanisms are used.

So, adding yet another pickle module is unnecessary. -- Alexandre _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
