// []byte -> base64 string
// bool -> json boolean
// nil -> Null
// string -> base64 encoded sequence of underlying bytes
// (u)int* -> integer, only value in -2^53..2^53 are allowed
// []interface{} -> json array
// map[type1]type2 -> json object with string keys marshaled as strings (not base64).

// arrays -> []interface{}
// maps -> map[string]interface{}
