yep, but in this case the name will be added anyway as a local of the 
module. So this make me think that it's not the original poster problem,
this should not occurs with module level name, it usually occurs on
method/attribute of classes in the module (since if __module__ doesn't 
match, there is no recursion on the object to find its methods and
attributes).
