In any case, it's simple to get the 2.3 behaviour back - just add __nonzero__. I think that could validly be considered a bugfix.

Alas not -- it would still be a functionality change relative to 2.4 and 2.4.1. Also, an object whose __len__() returns 0 but whose __nonzero__() returns True would be an anomaly. The best we can do IMO is to change it back in 2.5. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
