On this topic- we looked in to python2.6's new 'namedtuple' type,
which looked like it would be just the ticket for when you want
something a bit more readable than a tuple but faster than an object.
We were surprised to find they're substantially slower than tuples,
slower even than dicts, in fact not much slower than an object....
because they are in fact just objects. The interface would seem to
allow it to be implemented in a much faster way but that's not been
done yet. Maybe it will be in 2.7.
Perhaps we could at some time do our own C implementation of a
namedtuple type and see how it goes.
