There's no mention of the type of the class returned by NSObject.class. 
That type is NSObject.Class. Each Objective-C class has its own Class 
inner metaclass. Static methods are implemented behind the scene as 
members of this metaclass. This is already implemented.

As for interfaces, they should have a "meta-interface" too implemented 
by the metaclasses of those classes implementing the interface. I don't 
think this has been done yet.

It's probably an obvious observation, but why not use an annotation like:

 selector("insertItemWithObjectValue:atIndex:")
void insertItem(ObjcObject object, NSInteger value);

instead of the DIP's proposal of:

void insertItem(ObjcObject object, NSInteger value) 
[insertItemWithObjectValue:atIndex:];

This document and its experimental implementation predate UDAs. While I 
do like this syntax, I agree it'd make more sense to use an attribute 
now.
