MSGPACK_DEFINE_ARRAY equivalent?

[qiangxinglin]

IMO
MSGPACK_DEFINE_MAP == NLOHMANN_DEFINE_TYPE_INTRUSIVE, which would both add some boilerplate code into the class definition to make the custom type conversion. E.g.

struct person {
    std::string name;
    std::string address;
    int age;
};
<=>
{"name":"Ned Flanders", "address":"744 Evergreen Terrace", "age":60}

Is there any equivalent for MSGPACK_DEFINE_ARRAY?

struct Bounding_Box
{
    float x1, y1, x2, y2;
    MSGPACK_DEFINE_ARRAY(x1, y1, x2, y2)
};
<=>
[1.0, 2.0, 3.0, 4.0]
