I don't particularly agree, but if that's correct, then there's a large amount of change needed throughout the policy. These certainly aren't the only places this comes up. Ambiguous or not, I think the policy is mostly consistent in using python and python3 vice python2 and python3. At this point I think internal consistency is probably more important, so if someone wants to go through and make all the python's that should be python2, etc then please send in a patch. Scott K
