[Python-3000] PEP 3131 accepted

[Jason Orendorff]

This discussion is off the rails again.

I'm at least sympathetic to the spoofing argument, because theoretical
security concerns have a way of becoming serious practical concerns
overnight.

But I'm not sure what to make of the rest.  Other languages have had
this feature for many years.  The "numerous user interface problems"
do not seem to arise in practice.
