Ok, so, soon on CPAN (when I have time to write the PODs): 
package File::ScriptName;

use strict;
use warnings;

use version; our $VERSION = qv('0.1');
our $AUTHORITY = 'MASSA';

use Exporter q(import);
our @EXPORT_OK = qw(myname mybase mydir);

use Carp;
use Cwd qw(realpath);
use File::Spec::Functions qw(rel2abs);
use File::Basename qw(basename dirname);

BEGIN {
  my $myname = $0 = realpath rel2abs $0;
  my $mybase = basename $0, qw(.t .pm .pl .perl);
  my $mydir = dirname $0;

  croak 'chdir() used too early' unless -f $0;  

  sub myname { $myname }
  sub mybase { $mybase }
  sub mydir  { $mydir  }
}

Just use $0 (or File::ScriptName::myname) to find the real script name or use File::ScriptName::mybase and File::ScriptName::mydir for whatever purposes you want; traverses all symlinks and stuff... is it enough??
Update: croaks if you chdir before executing the module (possibly in a BEGIN block). Don't do that.

UpUpdate:It's on CPAN now, as scriptname...
