Thanks for the tip on enumerate, escaped me. Much like Kent's simply
using a temporary var escaped me despite having done similar things
often... never reply on a tiring Friday. On the bright side this
blunder with indexes, iterators, and lengths has made me more aware of
other contexts for using additional (zip, enumerate) facilities. I
hope the original poster learnt as much as I did from feebly
attempting to answer!

It's an elegant usage :-), zipping up slices of the same list to
compare consecutive elems in it, hmm neat.
