"Too expensive"? Are you worried about the time it takes to increment an integer 
counter in what is presumably a function call? If so, I'd be surprised if the 
cost were noticeable, given the function call overhead and likely memory hits. 
Might even be non-existent, depending upon the pipe-line and cache architecture 
of the machine.

Or did you mean "expensive" in some other sense?
