Parse JSON Object that contains Json string

Question

I want to parse a JSON Object that contains some value as a json string, note that I don't know those fields previously, so I can't do something like obj[key]=JSON.parse(obj[key]). I am looking for an easy way to do that,

obj={
  Name:"{\"FirstName\":\"Douglas\",\"LastName\":\"Crockford\"}"
}

And I want to get

{
  Name:{
      FirstName:"Douglas",
      LastName:"Crockford"
      }
}

If you want to get paradoxical about it, you can handle arbitrarily nested versions of this scenario using the "reviver parameter". Start by stringifying your object!

function parseJSON(k,v) {
  try { return JSON.parse(v, parseJSON); }
  catch(e) { return v; }
}
JSON.parse(JSON.stringify(obj), parseJSON);

Is that nifty, or is it just me?
