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.
