Hi,
First off and again, thanks for the support here. I think I can work for
the momement with your proposed implementation.
My problem is related to the fact that the list values of the GBK
defaultdict are plain list types, and thus cannot fire events for
operations on them. The testcase below do

say we have
p= Person()
p._address_by_role['r1']= [PersonToAddress(address=A
