I was bored, so here's a tie version:

package Status;

sub TIESCALAR {
  my $c = shift;

  my @v = @_;
  @v = ('|', '/', '-', '\\') unless @v;

  bless { vals => \@v,  status => 0 }, $c;
}

sub FETCH { $_[0]->{status} = ($_[0]->{status} + 1) % scalar @{ $_[0]-
+>{vals} }; return $_[0]->{vals}[ $_[0]->{status} ] }

package main;

$| = 1;

tie $s, 'Status';

while (1) {
        print $s;
        select(undef,undef,undef,0.1);
        print "\r" x 40;
}

Just pass in the sequence when tying:

tie $status, 'Status', qw( - + | + );
[download]

or let it default to the one you specified above.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
