brace spam + indentation levels for nothing.

I actually like the bracket+indentation as a section separator indicator. Usually I'll "group" fields/methods by common attribute:

   class Window
   {
       private {
           string _title;
           int _x, _y;
           // etc...
       }

       @property {
           auto title() { return _title; }
           auto x() { return _x; }
           auto y() { return _y; }
           // etc...
       }
   }

   // Or...

   struct Vector2(T)
   {
       T x, y;

       @property {
           auto xy() { return this; }
           auto yx() { return Vector2(y, x); }
       }

       @property static {
           auto zero() { return Vector2(0, 0); }
           auto one()  { return Vector2(1, 1); }
           // etc...
       }
   }

But I'm also use to C# code which is usually indented twice before you even get to functions (namespace -> class -> method).
