Actually, that is what I tried initially. Well, not as you have shown, but 
I created an empty list and then appended items to it. But Albatross later 
complained that my object had no __getitem__ method.

I must've had something else wrong with my code. I will have to go back and 
look at it again tonight.

Yes, I would think so, too. Which is why I tried that first.

Oh well, will try again later tonight...

Thanks for the sanity check.
