The current state of @property is that it doesn't really do 
anything. D allows you to call functions without parentheses, and 
to use assignment syntax to call a single-argument function, so 
you can write getters and setters that work like properties even 
if you don't use the @property annotation:


struct Example
{
     private int x_;
     int x() { return x; } // getter
     void x(int n) { x = n; } // setter
}

void main()
{
     Example e;
     e.x = 123; // calls setter
     int y = e.x; // calls getter
}
