You should probably change your sample usage to include the possiblity that the file couldn't be opened.

tie $var, "Tie::Scalar::Logged",
         'log.txt',
         '$var',
         [qw/all/] or die "Can't open log.txt - $!";

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
