I was perchance not clear - I had been doing stuff that
way for, well a long time.... not that this is crufty....
it still makes me nervous... these newFangledThings and all....

that I expect - and would have used up until your kvetch,
the first step foward was to skip the $index - you know
'chance it'.... this whole 'lisp' style of coding....
Oh I see, now I get where we slipped the disk....
srand was required up to 5.004....
and there is your FAQ
"How do I select a random element from an array?"
with the
$element = $thing[rand @thing];
as I originally coded it.....
