instead of:

struct A
	{
		virtual int operator <  (int i);
		virtual int operator <= (int i);
		virtual int operator >  (int i);
		virtual int operator >= (int i);

		static int operator <  (int i, A *a) { return a >  i; }
		static int operator <= (int i, A *a) { return a >= i; }
		static int operator >  (int i, A *a) { return a <  i; }
		static int operator >= (int i, A *a) { return a <= i; }
	};

shall be written this:

 struct A
 {
  int operator <  (int i);
  int operator <= (int i);
  int operator >  (int i);
  int operator >= (int i);
 };

 int operator <  (int i, A &a) { return a >  i; }
 int operator <= (int i, A &a) { return a >= i; }
 int operator >  (int i, A &a) { return a <  i; }
 int operator >= (int i, A &a) { return a <= i; }

  int operator >= (int i, A &a) { return a <= i; }



And even the D way is wrong.  Should be:

     struct A
     {
         int opCmp(int i);
     }
