Marek, you're wrong about this. A nullable int is of course not always an int.

Try compiling and running the following code:

using System;

class Program
{
        static void Main ()
        {
                int? i = null;
                if (i is int) {
                        Console.WriteLine ((int) i + 3);
                }
        }
}

When compiled with gmcs, this results in an InvalidOperationException (Nullable
object must have a value), while it should not.
