The discussion on SF doesn't really answer my question. What
Nick did is fascinating: he reused the type object implementation
to mimic a sequence ! That's cool, but looks like an awfully 
tricky way of doing something straight forward such as sub-classing
the tuple type to extend it with an additional dictionary.
So the question remains: why did Nick *have* to implement this
as meta-type ?

BTW, Nick's stuff is a nice intro to the more complicated capabilities 
of the new type system and I think people can learn a lot from it. 
I certainly want to learn from it, because I haven't really interned 
the details behind all the new C type slots yet.
