Since it doesn't express the authors intent. For example, assume you have a JSON Patch document like the following:

   [
     { "op": "test", "path": "/1", "value": 68 },
     { "op": "add", "path": "/2", "value": 105 }
   ]

What would you expect it to do? I think almost everyone would say that it set the third element of an array to 105 iff the second value is 68. So you might expect to get back an array on success but what you really get back might be something like this: 

{
  "some": "value",
  "1": 68,
  "some other": "value",
  "and": "finally",
  "2": 105
}

Maybe having something like ~2 to express that a number is to be treated as an array index would solve it!?
