Ralf, I think you are assuming a *lot* about what Brett wants to
accomplish.  The one example he showed gives me no reason to believe
that he wants to convert whole classes to/from Python tuples.  Maybe
he does really want that, and I just missed something... all he *said*
he wanted was:

  >>> obj.name_corresponding_to_several_cplusplus_data_members = some_tuple

For which to/from tuple conversions are little or no help.
