in reply to Data::Dumper for a Dummy

You are evaling the hash, not the content. 
use Data::Dumper;

my $content = q[<head><body>'body'</body>];

$hash{'name'} = 'a page';
$hash{'time_to_download'} = '3.23453';
$hash{'content'} = $content;

my $bob = Dumper \%hash;

# $bob = $VAR1 = { name => 'a page',
#                  time_to_download => 3.23453',
#                  content => '<head><body>\'body\'</body>';
#                };

eval $bob;
print Dumper $VAR1;

After you eval $bob you will find that $VAR1 holds the original hash. As long as the hash does not refer to itself you don't need to use should not need to set any flags.

I would agree that Data::Dumper is not the best tool for this, but it does work easily with simple hashes, and can be made to work with quite complex hashes.
