I have been thinking about this. AFAIU the slots are static data. So it seems a bit odd to calculate them with a (class) method. This seems a reasonable opportunity to use a class decorator or a metaclass. But I am in doubt about which would be the better solution here. -- Antoon Pardon. -- https://mail.python.org/mailman/listinfo/python-list
