I suspect that the very reason underlying the existence of this thread
is that some users out there are not quite ready to pull the plug on

Any decision about stopping the support of Python 2.6 should not be
taken solely on making the developer's life easier, but maybe I am
stating the obvious.

Thanks,
Armando
