in thread redeclaring variables with 'my'

If it were tightly de-allocating and re-allocating, is it not unreasonable to expect that they might end up at the same address? Not that I disagree with you; I'm hardly the expert. I rather think that what you say is actually the case.

But yah, I think tilly's hit it on the head.

    It would be reasonable, but it doesn't work that way. In fact here is a piece of code that triggers an illustrative bug in how it does work:
    recurse_lex(1); print "\n"; recurse_lex(2); print "\n"; recurse_lex(3); print "\n"; recurse_lex(4); print "\n"; sub recurse_lex { my $i = shift; my @array if 0; unshift @array, $i; print @array, "\n"; $i--; if ($i) { recurse_lex($i); } }
    Try that. It does something weird. And here are the details of what does happen.
      This makes sense. I wasn't disagreeing, though. :)
