Python 2 should be expunged from the planet, it is going to be the only
way of getting people to stop writing more Python 2 code that doesn't
work under Python 3.

Java has the same problem in that there are people out there still
running Java 1.4 just as Java 8 is about hit the streets. All JVM
instances prior to JDK8 should self-annihilate on 2013-03-31.

Whilst I agree large live systems do have to have carefully managed
change, I think D is not in the same backward compatibility game as
Python and Java. A big breaking change now is going to be much, much
less pain than storing up problems for later. But I already said that in
my earlier post. I guess I am just trying to bias the vote… ;-)
