When trying to pass around an object, Input::json() returns an array instead. When the request payload contains the following JSON object:

{"name":"John", "age":30}

The expected behavior should be:

$person = Input::json();
$person->name; // doesn't work

Instead each object property must be accessed as an array:

$person = Input::json();
$person['name'];

This used to work fine before the array_get call added somewhere around cd9fcd0.
