At the time you access the value $media{bond}, it does not yet exist. To get around this, you can do something like: 
$_ = "a:default:value" for @hash{'key1', 'key2', 'key3'};

# or

$hash{$_} = "a:default:value" for 'key1', 'key2', 'key3';

# or

@hash{'key1', 'key2', 'key3'} = ("a:default:value") x 3;

If you actually want one key of a hash to be an alias to another key, you'll have to do some tie() magic.
