Later today you posted "Differences creating tuples and collections.namedtuples" on python-list. http://thread.gmane.org/gmane.comp.python.general/726849
That *is* the proper place to make observations about current Python and ask questions about why it is the way it is and how to work around features that get in your way. So I will answer there, if I think more needs to be said, after reading the multiple current responses. Anyone else should do the same.
