While implementing a new Log::Dispatch output channel called Log::Dispatch::Perl (which is on its way to CPAN, but also available from http://www.liz.nl/CPAN/), I found that I cannot conveniently "lose" a number of levels of the message created by Carp::longmess, as seen if you do a Carp::confess.

The documentation says:

Packages claim that there won't be errors on calls to or from packages explicitly marked as safe by inclusion in @CARP_NOT, or (if that array is empty) @ISA.

Ok, so I added:

our @CARP_NOT = ('Log::Dispatch::Output','Log::Dispatch');
[download]

to my Log::Dispatch::Perl code. But a Carp::confess still lists levels with these modules:

use Log::Dispatch::Perl;

my $dispatcher = Log::Dispatch->new;
my $channel = Log::Dispatch::Perl->new( qw(name default min_level debu
+g) );
$dispatcher->add( $channel );

$dispatcher->alert( 'This is an alert' );
__END__
This is an alert
        Log::Dispatch::Output::log('undef','level','alert','name','def
+ault','message','This is an alert') called at /usr/local/lib/perl5/si
+te_perl/5.8.3/Log/Dispatch.pm line 95
        Log::Dispatch::_log_to('Log::Dispatch=HASH(0xfc578)','level','
+alert','name','default','message','This is an alert') called at /usr/
+local/lib/perl5/site_perl/5.8.3/Log/Dispatch.pm line 74
        Log::Dispatch::log('Log::Dispatch=HASH(0xfc578)','level','aler
+t','message','This is an alert') called at /usr/local/lib/perl5/site_
+perl/5.8.3/Log/Dispatch.pm line 22
        Log::Dispatch::__ANON__('Log::Dispatch=HASH(0xfc578)','This is
+ an alert') called at line 7

What am I missing?

Update:
Thanks ysth for the feedback. In the end, it has come to removing the first 4 lines from Carp::longmess. The actual regexp to remove the first 4 lines will become s#^(?:[^\n]*\n){4}##s. New version of Log::Dispatch::Perl is on its way to CPAN.

• 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).
