    def _post_setattr_a(x, y, z):
        print 'a'

# Attempting to initilize Test with values   
t = Test(a = 15, b = 16)
print t.a, t.b # print 16 both times
print t.get_member('a').get_slot(t), t.get_member('b').get_slot(t) # print 16 and None

# Demonstrating the different behaviours between using __set__ and get_member
t.__setattr__.__call__('b', 21) # _post_setattr_a is called
t.get_member('b').do_setattr(t, 42) # _post_setattr_b is called
print t.a, t.b # print 21 both times
print t.get_member('a').get_slot(t), t.get_member('b').get_slot(t) # print 21 and 42


#Here the problem seems to be that the wrapped __setattr__ does not access to 
#the right member. Direct access to the member works fine.
