Yes, please. One of the original arguments that delayed the
introduction of the collections module was the fear that it would lead
to the introduction of tons of subtly different data types, making it
substantially harder to choose the right data type for a given
application. I see this proposal as the realisation of that fear.

Unordered types can be a PITA for testing, for display and for generic
serialisation, so I definitely want to see a PEP before we add a new
one that basically has its sole reason for existence being "you can
iterate over and index the field values in a namedtuple".

Regards,
Nick.
