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.  :(
