I am trying to add some methods to a tuple. Obviously the example I posted
has been considerably simplified to just demonstrate the problem I'm hitting
;-))

Yes, but I want an object which has all the characteristics of a tuple with
additional methods.

I could use delegation to do this but subclassing appeared to be an easier
way.

I'm really quite interested in why this doesn't work. I *thought* I'd
grasped the concept of the new style classes but this seems to demonstrate
that I haven't!

Thanks for the response.
