At Ray's suggestion, go ahead and throw an error when the wrong type is read. Use the Type(obj) cast syntax (I was unaware that this would actually throw an error). Reading objects of a basic type like Array must still use "readObject(Array) as Array" so this is still supported, though not needed for user types.
