Hi,
If Python had method decorators @final (meaning: it is an error to override this method in any subclass) and @override (meaning: it is an error not having this method in a superclass), I would use them in my projects (some of them approaching 20 000 lines of Python code) and I'll feel more confident writing object-oriented Python code. Java already has similar decorators or specifiers. Do you think it is a good idea to have these in Python?
I've created a proof-of-concept implementation, which uses metaclasses, and it works in Python 2.4 an Python 2.5. See http://www.math.bme.hu/~pts/pobjects.py and http://www.math.bme.hu/~pts/pobjects_example.py
Best regards,

+1 on the idea. however, using a metaclass would be to limiting imho. can you implement it in a different way? a lot of things people use metaclasses for work perfectly fine without them (instead use a superclass that overrides __new__ or similar). -apnzi
