Yeah, but that's not something you'd have to do since you can 
just subclass it and add whatever you want there.

class MyThing: Reflectable {
  blah whatever;
}

@CustomTypeInfoExtension(new MyThing())
class Test {}


auto info = typeid(Test).rtInfo();
foreach(item; info.customItems)
   if(auto c = cast(MyThing) item) {
    // use c
   }


Or maybe we could implement it like:

MyThing c = typeid(Test).rtInfo().getCustomItem!MyThing();


which could perhaps be used with any type. You could also get 
compile time info on it easily enough:

class MyThing(T) : Reflectable {}

@CustomTypeInfoExtension(new MyThing!Test())
class Test {}
