Summary:
It would be excellent if NSJSONSerialization had an option to deserialize JSON into NSMapTable/NSPointerArray. Something like NSJSONReadingPointerContainers.

Differences vs current behavior:
The primary difference in this versus NSArray/NSDictionary would be that when deserializing to NSMapTable or NSPointerArray and there is a `null` entry in the JSON, the key/index would have nil in it, instead of `[NSNull null]`.

The same goes for transforming a Foundation object into JSON data, in reverse. If given NSMapTable or NSPointerArray and there is a nil entry, it would produce the `null` value for JSON.

Primary use cases:
This feels like it would allow for more idiomatic Objective-C to be written when dealing with JSON parsing. It would allow for nil-messaging when accessing collections (as opposed to having to special-case and check for NSNull).
