Is there a way to turn on tracing in perl (equivalent to bash -x)?

Question

I have a system script in perl. I need some equivalent of bash -x to determine what is going wrong with the script. Is there something equivalent?

EDIT: What bash -x

The Devel::DumpTrace module has been available since 2011.

Sample usage:

$ cat demo.pl
# demo.pl
# a demonstration of Devel::DumpTrace
$a = 1;
$b = 3;
$c = 2 * $a + 7 * $b;
@d = ($a, $b, $c + $b);

$ perl -d:DumpTrace demo.pl
>>>>> demo.pl:3:        $a:1 = 1;
>>>>> demo.pl:4:        $b:3 = 3;
>>>>> demo.pl:5:        $c:23 = 2 * $a:1 + 7 * $b:3;
>>>>> demo.pl:6:        @d:(1,3,26) = ($a:1, $b:3, $c:23 + $b:3);
