Could you clarify how you are calling this code and getting an unexpected error?

Thank you very much.

$ cat Devel/DB.pm
package DB;
sub file {
my $filename = shift // $DB::file;

return ${ "::_<$filename" };
}

sub DB {
( $DB::package, $DB::file, $DB::line ) = caller(1);

die ">$DB::file< ne >" .file( $DB::file ) ."<"
if $DB::file ne file( $DB::file );
}
1;

perl -d:DB script.pl

or for web application set this env
PERL5OPT='d:DB'
if this uwsgi you may add to the end of site.ini next:
env = PERL5OPT='d:DB'

The application I have try was a HTML::Mason, this is a complex app, about 500modules are loaded...
