Go ahead and actually implement it. It's not just one line in the

I don't even understand you now. First off, you just acknowledged that
this WILL impact CPython - you're not simply mandating what CPython
already does, you're tightening up the rules significantly. For others

Are you saying that the Jython project should simply die? Or that it
should become non-compliant with the Python spec? Huh?
