I like this, a lot. It could be a CPAN module if someone (push me and I'll do it) provided a mechanism where you could specify the output. Here's how I got around the tie-untie reference problem:

package Filter::Handle::Tie;
use vars qw/@ISA/;
use Tie::Handle; @ISA = qw/Tie::Handle/;

sub TIEHANDLE {
    my $class = shift;
    my $fh    = shift;
    bless { fh => $fh }, $class;
}

sub PRINT {
    my $self   = shift;
    my $fh     = *{ $self->{fh} };
    my($file, $line) = (caller)[1,2];
    print $fh sprintf "%s:%d - %s\n", $file, $line, join ' ', @_;
}

This avoids the deep recursion by not printing to a tied filehandle -- it's copied by dereference before printing to it.

Maybe users could pass in a subref with stuff they want to print instead. Interesting idea.

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.
