Super Tuples

    Paul> j = mytuple[someconstantpool.someconstant]

Ah, what you want are the equivalent of C's enumerated types.   Why not
abstract that into a distinct feature so you can use the same technique with
lists and dicts?

    >> What's the result of
    >> 
    >> time = (hour=24, minute=00, second=00)
    >> point = (x=1, y=2, z=3)
    >> 
    >> time = point

    Paul> "time" is an alias for "point"! Python doesn't do type checking of

Yes, I realized that shortly after hitting "send".
