Python COM and IDispatchEx

[Donavon Keithley]

I see that Python server objects expose IDispatchEx, but they don't seem to
support expando behavior.  The following attempt to add a member returns
"member not found" (where pDispEx points to a Python object):

DISPID id;
HRESULT hr = pDispEx->GetDispID(CComBSTR("NewMember"), fdexNameEnsure, &id);

Am I doing something wrong?

On the client side, Python doesn't seem to query for IDispatchEx.  My object
will happily add new members through Invoke ("obj.NewMember = 123"), but
"del(obj.NewMember)" fails with "AttributeError: delete non-existing
instance attribute".  Member enumeration would also be nice.

It seems that, in principle, Python objects should map pretty cleanly to
IDispatchEx and vice versa.  Is this planned for future versions?
