Yes. I haven't been able to get them to work.

I had a variant of HelloWorld -- actually based on LBW (LittleButtonMouse)
but creating a Python class instance to register as a delegate.
Registering the delegate seems to work but it never gets called.

After this discussion of name mangling, I was just wondering if I
misnamed the methods in Python:  "applicationShouldTerminate_" , etc.

I tried a simpler program using my own defined notifications and
posting it myself so I had more control over what was going on --
it gets a bus error after posting the notification.

I tried running it under gdb to see if I could find what was wrong --
my conclusion from that is that I'm going to have to build an
objc-runtime from Darwin sources with debugger info and sources
online so that I can step thru the objc-runtime code -- which is
where things seem to go wrong. ( Not that it's the objc-runtime --
I'm pretty sure the problem is pyobjc-runtime, but to find that bug I
think I  need to back up from the error in the objc-runtime.   )
