We agree on the Joe advice.
But to me, using L -- O is obfuscation.  It would be *harder* for
me to understand that code than say a version using

No, let's be honest here.
It *WAS* quite a bit harder for me to understand the L -- O
version because I had to stop, check the documentation, try
a couple of tests, all to verify that the results came out in
the right order.

I quite agree that sometimes a bit of brute force *can* help you
get to working code quicker.  But it has to be *obviously correct*
brute force.
