=> I reached the same conclusion!

                                        ^ 3

=> not only most systems are still with old 2.7 but there are a few with
even older versions! I got a bug report (there are rare so I remember
each of them) for the AFTR/PCP code about the standard

if sys.version_info.major > 2:
    raw_input = input

which failed on CentOS 5.5 with:
AttributeError: 'tuple' object has no attribute 'major'
So now I have a try:

try:
    if sys.version_info.major > 2:
        raw_input = input
except AttributeError:
    pass

In conclusion 2.7 won't save us... and the decision to start directly
with Python 3 was IMHO very good.

PS: version_info named components is Issue4285 if you want the history
so the idea is 4 year old...
