How to parse a json node that contains children of different types?

[Bagomot via Digitalmars-d-learn]

I have a json like this:

```json
{
   "arguments":{
      "jvm":[
         {
            "rules":[
               {
                  "action":"allow",
                  "os":{
                     "name":"osx"
                  }
               }
            ],
            "value":[
               "-XstartOnFirstThread"
            ]
         },
         "-Djava.library.path=${natives_directory}"
      ]
   }
}
```
Here the "jvm" node is an array that has different data types for 
its elements (json object and string).

I am using [asdf](https://code.dlang.org/packages/asdf) library 
to deserialize json. I am trying to deserialize this json into a 
structure like this:
```d
struct Arguments{
    @serdeKeys("jvm")
    Object[] jvm;
}
```
But there is a problem with different types. I understand that 
Object[] is not suitable here, but I don’t know how to do it.

I ask you to help me with this.
