DSL: Compose query with all nested fields included

Hello!

I'm building my query dynamically. I want to select all the nested sub fields _(children, grand children etc)_. Is there a way to accomplish this with `gql`?

I'm not very fluent in graphql but I do know it's possible to build infinite nested queries, so is it even possible/easy to prevent that from happening?

I've experimented with looping through `ds.Content._type.fields` to somehow select each field and any children they might parent. But I find it confusing as some objects contains `of_type` attribute while others do not and I don't know why that is.

Might I be better off doing an introspection with

```graphql
{
__schema {
types {
name
fields {
name
}
}
}
}
```

and determine any children by simply parsing the json data? Seems redundant.
