Nick, thanks for the much better implementation than I achieved; you seem to have the same goals as my implementation. I learned a bit making mine, and more understanding yours to some degree. What I still don't understand about your implementation, is that when adding one additional line to your file, it fails:

w = named_value("ABC", z )

Now I can understand why it might not be a good thing to make a named value of a named value (confusing, at least), but I was surprised, and still do not understand, that it failed reporting the __new__() takes exactly 3 arguments (2 given).
