Ability to verify stringified JSON

[Vantuz]

Hello! Is there a way to verify stringified json as in this stackoverflow question? If no, are there plans to implement this feature? If no, would it be possible for me to implement this feature and contribute it as a pull request to this repo?

Pull requests are always welcome. But I don't know how you will able to know that you need to parse a field in the middle of a payload as JSON and then recursively match it.
