That does not negate what Tim, Paul, and myself (among others) have been
saying: you're going to be unsuccessful in trying to introduce undefined
behavior in Python. Give it up already.

I believe that you have a possibility to get Guido to define a language
feature that says "it operates <thusly>, but on <xyz> it will operate
like <this>." The assert statement and some JPython-related issues are
examples. However, this is the wrong forum for this since it is *VERY*
dependent upon Guido's thoughts.

As I've said before: bringing up this issue is growing awfully tiresome. I
wish you would stop.

Happy Holidays,
