The somewhat strange syntax was to demonstrate the localisation of the index variable which I wasn't aware of :) As to using why you would want to do this, if you exit the loop at any point before the final iteration the count of elements may not be useful but the last value of the index variable will tell you when you left... no doubt there are better ways to do the same thing but I wasn't playing with production code I was just playing and I noticed something I didn't expect :)
the c-style loop still bothers me, OK I can now see why it is greater than the last increment but it seems wrong that the variable contains this value outside of the loop when you have explicitly asked it to stop before you got there! Of course if I used the loop as intended I would never have noticed... or if the index variable was localised as in the perl style loop.
