Hrm. The underlying issue is that MonoTouch uses C# attributes to do some
magical Objective-C binding under the hood.

One normally writes (in C#):

  [Register ("AppDelegate")]
  public class AppDelegate : UIApplicationDelegate {
  }

  public class Application {
    static void Main (string[] args) {
      UIApplication.Main(args, null, "AppDelegate");
    }
  }

but if I try to write this bootstrap code in Java:

@RegisterAttribute.Annotation("AppDelegate")
public class AppDelegate extends UIApplicationDelegate {
}

(with the Application class still defined in C#), then it fails, claiming
that no class exists that is annotated as "AppDelegate".

Clearly there are other places where things could be going awry, but the
anomalies that I saw in the disassemblies seemed like a useful place to
start.

There should (in theory) be no difference between the above two snippets of
code, right? (Assuming the imports are the same, which they are.)
