That is what I am saying.

I /think/ it's only dict, but I haven't played with subclassing lists, tuples, etc. It's not a C vs Python issue, but a
'implemented with __private methods' issue. From what I have seen so far in the confusion and frustration that decision
has caused, I do not think it was a good one. :(
