Hi,

I've a class which subclasses PersistentList and which has a mixin:

class Confused(PersistentList,MyMixin):

    def __init__(self,*args,**kwds):
          #init stuff
          super(Confused,self).__init__(*args,**kwds)


Previously, it subclassed PersistentObject and all worked fine. When I
changed it to subclass PersistentList I found that that MyMixin was not
initialising. This seems to be because PersistentList defines an
__init__ method which doesn't call super() whereas PersistentObject
doesn't define an __init__ method at all.

This seems to be fixed by the addition of:

super(PersistentList,self).__init__(*args,**kwargs)

on line 18 in PersistentList.

Presumably the same issue would occur with PersistentDict.

Is this behaviour by design, or would it be a good idea to add these
super() inits calls to the Persistent classes so they play well with
subclasses?

Thanks very much, by the way, for developing and maintaining durus. It's
a pleasure to work.

Regards

Patrick
