[ 2374934 ] Failed to recreate a list

In the following JSON code a list is recreated:

```
"A" : [1,  2],
"A" : [3,  4]
```

Result:

`Error: 'argument of type 'int' is not iterable`

But expected:

`"A"` with value `[3, 4]`

Cross check

The same with a dictionary:

```
"B" : {"param1" : 1},
"B" : {"param2" : 1}
```

Result (like expected):

`DotDict({'B': DotDict({'param2': 1})})`
