At last night's Nerd Dinner, Brian Henderson was talking to Glenn Block and me about this problem.  He suggested a language feature of some sort, with perhaps the feeling of generics.  He mentioned that there really isn't anything to make properties easier, other than the automatic properties of C#, but those aren't very flexible. I crafted a syntax that...
