Can you clarify--do you consider $x in my example a global, since it's
file-scoped?

But my point was that you can, if something outside has a reference to
$a or $b. I was referring to $a through $x. $x is perfectly good
whether we returned $a or $b. This doesn't require globals (unless
you're calling a file-scoped lexical a global).
