snipThe following bits of advice are stylistic in nature, so you can ignore them, but there really are good reasons not to. As name, $x does not really mean anything in this context. A better name is $k for key, especially if you use $k often to mean key. The fat comma (=>) is better than the normal comma in this case. They will function the same way, but the fat comma makes it clear that there is a key/value pair being created. -- Chas.
