Actually, Unladen Swallow is now targeted at 3.1; its developers have 
conservatively proposed its integration in CPython 3.3. I would not be 
completely shocked if it happens in 3.2.

Almost everything is 'arguable'. Based on experience, Guido never 
expected major uptake until 3.2 (a year away).

Just who produced that? and why?

Does not exist yet, but again, coming from the same devs for the purpose 
of helping transition to 3.x.

Unlikely to ever exist.

You have to wait another 9 years to really say that. However, my 
impression is that Python 3 alreays surpasses Perl 6.
