public static void Main() {
typeof(Program).GetProperty("GetMe", BindingFlags.NonPublic | BindingFlags.Static);
}
private static int GetMe {
get { return 0; }
}
(you need to OR NonPublic and Static only)

Why doesn't Java Map extend Collection?
...? That said, I am mostly convinced already of why this is not such a great idea as I once thought, but I still think it's worthy of further debate, if only to enrich my own understanding of what makes a good API/OOP design.
