Guido bumped into this about a month ago, noting that he thought it was a bug in current Python trunk that the PEP restrictions are followed now. I replied that I thought it was a bug in released Pythons that the PEP restrictions were not followed: http://mail.python.org/pipermail/python-dev/2006-January/060247.html Doesn't look like Guido responded, so I'll channel him and declare that he intended to agree with me after all ;-)

It was so obvious that you were right I didn't bother to agree at the time. But yes, I agree. And I swear on a stack of Python 1.5.2 language reference manuals that you didn't have to twist my arm. :-)
