I feel like I'm repeating the PEP, but here it is again anyway. There
will be messages in the docs and pending deprecation warnings (which
don't show up by default but can be requested) starting in Python 2.7
and 3.2. Regular deprecation warnings wouldn't show up until Python
3.4, 3 years away. This compromise was intended exactly to address the
issue you brought up about people getting over the Python 3
transition.
