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.

RE (tilly) 4: redeclaring variables with 'my'

    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. :)
