  Off hand I would say because it doesn't go to anything (Open the 
box... What do you mean what box? That invisible one over there 
can't you see it!?)...

  Might be better to ask in D.learn, I try and refrain topics 
unless it actually is in more depth or requires advanced answers.

Consider...

@property int sq(int x) { return x * x;}

void main(){
   int x = 5;
   writeln(x.sq); //should print 25
}
