I have a hybrid property with a custom setter defined for a one-to-many 
relationship on one of my classes, and for assignments using the = 
operator, it works fine.  I can assign a new list of objects to that 
property, and it calls the setter to handle the details.

But when I use the append() method on the list, the setter is not called.

How do I change this behavior?  I would like to be able to append, so I 
don't have to do silly things like obj.property = obj.property + [new].  
That's not very Pythonic.

Thanks,

Avi Blackmore
