New submission from Hagen Fürstenau <[EMAIL PROTECTED]>:
After pickling a set of ints with Python 3.0 and pickle protocol 2:
[EMAIL PROTECTED] ~]$ python3.0
Python 3.0b3 (r30b3:65927, Aug 21 2008, 11:48:29)
[GCC 4.1.0 20060304 (Red Hat 4.1.0-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> f = open("test", "wb")
>>> pickle.dump({1,2,3}, f, 2)
>>> f.close()
I get the following error when trying to read this with Python 2.6:
