Another option is to use the AUTOLOAD feature, and determine valid tag toggles using a hash rather than an array (although there's no reason you couldn't generate the former from the latter)...

my %state = (
  name    => 0, # default states
  gender  => 0,
  address => 0,
);

sub AUTOLOAD {
  my $tag = $AUTOLOAD;
     $tag =~ s/^.*:://;

  my $turn_off = $tag =~ s/_$//;

    # Only keep track of tags we want.
  return unless exists $state{$tag};

  $state{$tag} = $turn_off ? 0 : 1;

    # Do something that uses %state
  whatever();
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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.
