Yes! It works just fine, and I like how concise and clear the code is
compared to mine. Unfortunately, it isn't quite as fast -- on my machine, a
million iterations of your routine took about 6.3 seconds, while a million
iterations of mine took about 5.8 seconds. The reason for this (I believe --
somebody correct me if I'm wrong) is that Euphoria's built-in find()
function can run thru the elements of a sequence faster than Euphoria's
"for" loops can.
