Xavier, why do you think that is the correct approach? The docs say
"The need for this class has been largely supplanted by the ability to
subclass directly from dict (a feature that became available starting
with Python version 2.2)."

If you mean that Sergey should subclass _in this instance_ could you
please explain why? (Sorry if you already have, I never saw your
original post...)
