Not unless it is so declared my $a :shared.
What the value is without the attribute, I won't even think about.
Are we going the fork() route where the current value is cloned, or perhaps
something else entriely.
Would making closures only under direct instructions be something useful?
It would add some typing, but would be a guide to both the reader and
perl (and perhaps, prevent some unanticipated closures from being created.)
