	### Nested tools
	Tools can contain nested values. It is possible with the `array` type.
	Let the JSON input be the following:
	```
	{
	"blocks": [
	"type": list,
	"data": {
	"items": [
	"first", "second", "third"
	],
	"style": {
	"background-color": "red",
	"font-color": "black"
	}
	}
	]
	}
	```

I think it should be...

{ 
     "blocks": [
         {
             "type": "list",
             "data": { 
                 "items": [ 
                     "first", "second", "third" 
                 ], 
                 "style": { 
                     "background-color": "red", 
                     "font-color": "black" 
                 } 
             } 
         }
     ] 
 }
