These lists will decrease during processing and will normally contain one
element, so to know if a list is definitely treated I need a flag.
Why? You can find the size of an array like so:
$size = @array;
In the case of an array reference, it's merely
$size = @{ $aref };
What are you doing that leads you to believe you'll need a special marker
of some sort to indicate that an array has been processed?
