Support format {"property":{"lang1":"localized message in lang1"}}

[ghost]

I am working in a project in which we want to process a json such as:
{ "id":0, "name":"monopoly","description":
{"en":"Monopoly is a board game that originated in the United States in 1903"
,"es":"Monopoly es un juego de mesa de intercambio y de bienes raíces"
}}

I like the easiness of this library and would like to contribute a patch to allow processing this kind of formats. I imagine it like this:

String.toLocaleString(retrievedObjectWithLocalizedData,"reverseFormat");
"description".toLocaleString();

We want to opt for this format because the localized data is editable and stored in the database.
As such, it makes a lot of sense to return localization values together with queried data.

Do you find it worth the extra complexity and effort as to accept a PR?
Do you have some feedback, syntactic preferences, or any concerns?
