 //
 // A Value represents something that can be stored in JSON or passed to/from
 // JavaScript. As such, it is NOT a generalized variant type, since only the
 // types supported by JavaScript/JSON are supported.
 //
 // IN PARTICULAR this means that there is no support for int64 or unsigned
 // numbers. Writing JSON with such types would violate the spec. If you need
 // something like this, either use a double or make a string value containing
 // the number you want.
