With the cursor sitting on this line in the debugger, I tried:

It is obvious that my instance has been created, and installed into the methods instance via _setObject(), so I am baffled as to why folder[id] works but getattr(folder, id) does not.
Can anyone shed any light on this, for me? Am I trying to do something that's outside the capabilities of ZClasses, or have I just missed something obvious?
Currently, ZClass instances can only be added to objects which store them in a way accessible with getattr. And evidently, ZClasses themselves do not do that, so you can't add a ZClass instance to a ZClass. This is a bug in the ZClass instance logic, and I know Michel Pelletier knows about it (at least, another place where it shows up), but I don't know if it has been reported to the collector or a fix is actively in the works. I may take a look at this and see if I can submit a patch to speed the fix process, as putting ZClass instances into ZClasses is something which will be very important to me in the near future.
