It would be very hard to write 2.6 code that is completely compatible

including even the "print" statement, which in 3.0 is a function (syntax
change).

I am not sure how far the from __future__ import feature will work for
such changes as that.

 Sigh...

from __future__ import print_function

...can everyone who isn't involved in writing python code, and/or not
read about 2.6 / 3.0 before this thread please not comment?

Not defined in older versions of python however, hence the need to branch code, hence a problem with EPEL supporting code.

 As Toshio Kuratomi said extremely well, in the grand parent to this
post:

        Note that I think this decision is only partially within the
        powers of the Fedora Project to decide.  If 80% of our upstream
        libraries move to py3, we'll need to move to py3 sooner.  If 80%
        refuse to move off of py2, we can take our time working on
        migration code.

...so as I said, we don't have concrete plans yet ... and some of that
is because it depends on available resources within the project, but a
lot of that is because we have to follow upstream and it's not obvious
how fast (the majority of) python developers upstream will move.
