Are you telling me that the ONLY thing you use dictobj objects for is to
print them?

I don't think so. I do know how to print an object, amazingly.

Perhaps you would like to explain how you use the rest of the
functionality of the dictobj, instead of taking my words out of context
and giving an inane answer.

Why jump through all those hoops to get attributes when Python already
provides indexing and attribute grabbing machinery that work well? Why do
you bother to subclass dict, only to mangle the dict __getitem__ method so
that you can no longer retrieve items from the dict?
