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, unless I could be sure that would be called while the class structure is still around. That could be resolved by taking a copy, of course, but that is messy. This also relates to one of my problems with the callback. I am not being called back if the class is still live at program termination; ones that have had their use counts drop to zero do cause a callback, but not ones whose use count is above zero. I am not sure whether this is my error or a feature of the garbage collector. If the latter, it doesn't matter from the point of view of freeing space, but is assuredly a real pain for producing statistics. I haven't looked into it, as it is not an immediate task.
