Not the parent, but my biggest issue with arrays and nested objects is this:

Most JSON arrays come in the form

    {
        "objects": [{"foo": "bar"}, ...]
    }

Instead of `[{"foo": "bar"}, ...]`. So I need to create a temporary struct, it would've been nice to be able to provide a starting point or similar. Like `json.UnmarshalFrom(data, &foos, "objects")` (hmm, this gave me an idea!).

Another example is this:

    type Address struct {
        street string
        city   string
    }

And I want to parse that populate that struct with the data from

    {
        "name": "John Doe",
        "address": {
            "street": "Some street 1",
            "city": "Footown"
        },
        ...
    }

Again I have to use temporary struct.

Sorry I actually meant Lists. In Java List<String> is just List (since they aren't reified) at compile time so you have to explicitly deserialize an String[] and then manually throw it into an ArrayList<String>.
