Thanks Frank. Good approach!
One question - You could do:
class MainObject:
def __init__(self, identifier):
self._del = delwatcher(self)
then later
class delwatcher:
def __init__(self, tobject):
self.obj_type = type(tobject)
self.identifier = id(tobject)
...
when creating delwatcher. Was there special reason to not to use them?
is this because of memory is reused when objects are deleted
and created again so same reference could be for objects created
in different time slots?
Thanks
