These are my classes
class MyDate
{
    int year, month, day;
}
class Lad
{
    string firstName;
    string lastName;
    MyDate dateOfBirth;
}
And I want to turn a Lad into a JSON string like:
{
    "firstName":"Markoff",
    "lastName":"Chaney",
    "dateOfBirth":
    {
        "year":"1901",
        "month":"4",
        "day":"30"
    }
}
Other than manually developing a JSON string writer, is there any other option?
