I have created a DIP for making D ABI compatible with Objective-C. This idea has already been announced, what I've done now is created a proper DIP. The DIP is basically Michel Fortin's original designed document properly formatted and put next to the other DIP's.

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.
