[ZODB-Dev] PersistentMapping copy

[Joshua Reynolds]

Howdy all,
Sorry if I'm totally out of the loop here.

Is there any compelling reason not to have a copy method on 
PersistentMapping?  I am trying to update to the latest ZODB and i see 
that it is gone.  I was thinking something along the lines of

     def __copy__(self):
         return PersistentMapping(self.data.copy())
