When I said "carrots" I meant everything that makes Python 3 the best
version of Python, including the backward-incompatible changes.
I guess I have more confidence in Python 3 than you do. I don't see

I don't view it as artificial but simply a focusing of the development team
on what has been determined as the future of Python by Guido and letting go
of the past.
IMO keeping Python 2.x around past 2.7 is the equivalent of python-dev
saying "Python 3 is the future, but we are keeping the old Python 2.x around
because we don't have *that* much faith in the future we have laid out".
That's poison to Python 3 by showing a lack of confidence in the direction
that the BDFL and python-dev as a group has chosen. Now I could be wrong and
there could actually be a large number of active contributors who want to
keep the 2.x series going, but based on the discussion that occurred the
last time this came up I believe the guys who are keeping Python running are
ready to move on.
