As 'this' is not available in static member functions; you mean

     static S opCall(int x, int y)
         S s;
         s.x = x;
         s.y = y;

         return s;

But that is basically the constructor. I don't understand why opCall 
gets in the way in

   auto s = S(1, 2);

The right hand side should call the constructor. Only after an object is 
constructed, should opCall be used:

   s(3, 4);

That's what I expected, but there must be a rationale... :)

Not with dmd 2.037. :(

I've responded to your message on the other thread titled "struct 
members not default initialized?". It turned out to be a bug that was 
reported about a year ago:
