This is how I would do it:

class Point
{
     private int x_;
     private int y_;

     this (int x, int y)
     {
         x_ = x;
         y_ = y;
     }

     int x ()
     {
         return x_;
     }

     int y ()
     {
         return y_;
     }

     int x (int x)
     {
         return x_ = x;
     }

     int y (int y)
     {
         return y_ = y;
     }
}

If I don't have a conflict with methods I just drop the underscore and 
use "this." in the constructor:

struct Point
{
     int x;
     int y;

     this (int x, int y)
     {
         this.x = x;
         this.y = y;
     }
}
