Well, Perl would guarantee the order. I can see situations where it'd
be better to force a random pick to avoid starvation proble

Also known as constructs you wish you hadn't discovered.
So, I'm reading through Finkel and I came across the following, which
computes the greatest common divisor of a and b (recast into perl6ish
syntax)
while {
when $a < $b { $b -= $a }
when $b < $a { $a -= $b }
}
The idea is that
