One objection I have with json_spirit is that its value is rather
heavy memory wise, and also forces initializing all of the members.
Maybe that's no longer true, I got the code below in Mar09. I think
something boost::variant-based would be more suitable (incorrectly
mentioned using tuple in my first post, when I meant variant). --DD

namespace json_spirit {
    enum Value_type { ... };
    typedef std::vector< Pair > Object;
    typedef std::vector< Value > Array;

    class Value { ...
    private:
        Value_type type_;
        std::string str_;
        Object obj_;
        Array array_;
        bool bool_;
        int i_;
        double d_;
    };
}
