Just out of sheer curiosity, I wonder which would be more CPU-effective; doing the counter increment and a modulus/numeric comparison in the ternary; or the string comparison in the ternary. I know it's academic in respect of the computing power we have these days, but being brought up on machines with limited memory and slow processors.... Old habits die hard.
