**************

UPDATE: Figured this out myself. I needed to add $Data::Dumper::Deparse = 1;

**************

I'm debugging a program that passes around coderefs as part of an html reformat. FWIW, the coderef winds up being an argument to Html::Element::look_down.

It would be convenient to examine the contents of the coderef. I was hoping to be able to do this with Data::Dumper, but I haven't figured out a way to do this. Data::Dumper did have some examples that seemed to touch on code refs, but they don't seem to do what I want.

Is there a way, Data Dumper or otherwise?

Looking for something along the lines of 

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use Test::More qw(no_plan); 

$Data::Dumper::Deparse = 1; # I needed to add this 
 
my $subroutine = sub { print "test" };

print Dumper($subroutine); #nah, this just gives "$VAR1 = sub { "DUMMY
+" };"

my $wanted = 'print "test"';
my $got = get_code($subroutine);

is($got, $wanted);

sub get_code {
    defined(my $coderef = shift) or die "no code ref";
    return "whatever";
}

Thanks for leading me to better perl!
