Hi,

I have here a simple script (https://gitorious.org/json_diff/mainline)
which makes a diff between two JSON files. So for JSON objects

{
     "a": 1,
     "b": 2,
     "son": {
         "name": "Janošek"
     }
}

and

{
     "a": 2,
     "c": 3,
     "daughter": {
         "name": "Maruška"
     }
}

it generates

{
     "append": {
         "c": 3,
         "daughter": {
             "name": "Maruška"
         }
     },
     "remove": {
         "b": 2,
         "son": {
             "name": "Janošek"
         }
     },
     "update": {
         "a": 2
     }
}

(obvious problems with name conflicts between internal keys and the
investigated keys will be somehow addressed later; any simple Pythonic
suggestions how?)

Use '_append', etc, much like namedtuple does, for the same reason.
