Sorry about a second message, but I mentioned this aspect earlier,
and it is semi-independent.
If I want to produce statistics, such as the times spent in various
operations, I need a callback when the class is disposed of. Now,
that WOULD be inconvenient to use the C object attribute callback,

Yes, I thought of that, but a custom metaclass to provide one callback
is pretty fair overkill!

details of how to do it! After 30 years, I can't say I am surprised.
But I need to clean up workspace when a class (not object) is
deallocated. I can't eas
