How can I create a dict that sets a flag if it's been modified

[Amit Khemka]

Ideally, I would have made a wrapper to add/delete/modify/read from
the dictionay.

But other than this, one way i can think straight off is to "pickle"
the dict, and to see if the picked object is same as current object.

cheers,
amit.
