jessenoller.com - Guido van Rossum’s Weblog: Python 3000 Status Update (Long!)
Tres interessant dans l'évolution d'un langage. Une version intermédiaire envoyant des warnings sur ce qui ne marchera pas à la prochaine version. A reflechir.
Python 2.6 will support a "Py3k warnings mode" which will warn
dynamically (i.e. at runtime) about features that will stop working
in Python 3.0, e.g. assuming that range() returns a list.
