Hi Phil, I have the personal habit of using __slots__ to explicitly list all "member variables", i.e. instance attributs my classes have. IIRC, the original intention behind this was to allow for efficient classes, i.e. ones that do not have one __dict__ per instance. But as a side effect, this leads to exceptions being thrown when one tries to add attributes that were not specified, and I am using this as a desired constraint, i.e. I want to force myself to specify the attributes I use in the class, as a sort of developer documentation.
However, this fails as soon as one of the base classes has a __dict__, and guess what? QObject and friends have. Is there a good reason why this must be the case, or would it be a desirable feature of SIP to suppress the __dict__s? (BTW: boost::python does so unconditionally.) I can imagine that people are used to "attaching" data members to widgets, but I would happily ditch this and instead get notified about incomplete __slots__.
