Thank you for this.
Do you think such cross-version support would have been easier or harder
if the major changes and deletions in 3.0 has been spread over several
versions, such as 2.5 - 2.7. In other words, suppose the Python 3 idea
never occurred to anyone and
2.5 dropped the old int division and finished the unification of int and
long.
2.6 dropped classic classes and switched range, filter, and map to their
iterator versions.
2.7 made unicode the text type
This is not purely a hypothetical question since the issue of spreading
or bunching changes may arise again in the future.
