Hello,

I have run into a problem with 'my' and some bad code. I would like to know how Perl handles this situation.

The code looks something like this: 

sub foo {
  my $string .= 'appended stuff' if ($conditional1);
  $string .= 'more appended stuff' if ($conditional2);
}

The code does not fail syntax checking. Under mod perl (Apache::Registry) I am getting shared memory issues across daemons.

If $conditional1 is false:

  1. what is the scope of $string?
  2. is it declared?
  3. is it initialized?

This works fine, btw. 

sub foo {
  my $string = '';
  $string .= 'appended stuff' if ($conditional1);
  $string .= 'more appended stuff' if ($conditional2);
}

Thanks for any help.
