replacing __dict__ with an OrderedDict

[Eelco]

i havnt read every post in great detail, but it doesnt seem like your
actual question has been answered, so ill give it a try.

AFAIK, changing __dict__ to be an ordereddict is fundamentally
impossible in python 2. __dict__ is a builtin language construct
hardcoded into the C API. There is no way to mess with it.

Apparently this is different in python 3, but I dont know much about
that.
