this is a bug in astng. I've added a ticket so this should be fixed in
the next astng release:

http://www.logilab.org/ticket/5626

Meanwhile i don't see anyother way than using a global variable outside
the class scope, for instance:

MEMBER = 10
class foo:
     member = MEMBER

     @decorator(MEMBER) 
     def test(self):
          pass

thanks for the report!
