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).
