I don't think that "id" is particular interesting. Apple is moving away 
from it more and more. They added the "instancetype" feature for the 
declarations of "init" and "alloc". They added generics for containers.

For a generic type to store any kind of object I would recommend using 
"NSObject" which is (in practice) the root of all classes. NSProxy is 
the only class I've seen which doesn't inherit from NSObject. Although 
it still conforms to the NSObject protocol.

I would recommend against using "id" to store both objects and C types.
