I have to admit that I often use this form, rather than bracketing.   
My logic is not that it saves space (as you have demonstrated it  
doesn't), but instead that it makes my code easier to read and  
brackets easier to match -- I'd rather have the additional dollar  
signs than the additional brackets to count.
