in reply to Printing the code of a coderef

You can also try using Data::Dumper... just set $Data::Dumper::Deparse to true.
use Data::Dumper;
$Data::Dumper::Deparse = 1;
my $code = sub { print "hello world\n" };
print Dumper $code;
__END__
$VAR1 = sub {
                  print "hello world\n";
              };

A more interesting example: 
{
  package foo;
  use strict;
  sub get_coderef { sub { print "hello world\n" } }
}
use Data::Dumper;
$Data::Dumper::Deparse = 1;
print Dumper(foo->get_coderef);
__END__
$VAR1 = sub {
                  package foo;
                  use strict 'refs';
                  print "hello world\n";
              };
