That's both interesting and intriguing. Is the behavior documented other than in the source? Is it reliable? How does Perl decide when to GC a subs lexicals and when not to? How does it know when a sub might be called again?

Examine what is said, not who speaks.
1) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3) Any sufficiently advanced technology is indistinguishable from magic.
