use Perl

Just another reason to love Data::Dumper which is, in my opinion, the best module in perlland. Pay close attention.

Suppose you have this data structure:

my $ref = { a => sub { print "a"; } };

Data::Dumper dumps it as:

$VAR1 = { 'a' => sub { "DUMMY" } };

Because it doesn't print out sub references. But you can tell it to deparse them (through B::Deparse) by setting $Data::Dumper::Deparse:

use Data::Dumper;
$Data::Dumper::Deparse = 1;

my $ref = { a => sub { print "a"; } };
print Dumper $ref;


produces

$VAR1 = {
 'a' => sub {
  print 'a';
 }
};


I didn't know this feature existed, and was considering creating a new module to mix Data::Dumper and B::Deparse.
