The proposal in your email seems incomplete -- there's two paragraphs on the actual proposal, and the entire rest of your email is motivation. That may be appropriate for a PEP, but while you're working on a proposal it's probably better to focus on clarifying the spec. Regarding that spec, I think there's something missing: given a list (or tuple!) of values, how do you turn it into an 'ntuple'? That seems a common use case, e.g. when taking database results like row_factory in sqlite3. -- --Guido van Rossum (python.org/~guido)
