Not quite. I'm suggesting a factory function that works for any value, and derives the parent class from the type of the supplied value. 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 = namedvalue("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).

Can I suggest that an enum-maker be offered as a third-party module rather than prematurely adding it into the standard library.
