Why??

To get an element from a hashref, you take the normal code for getting a hash element:
$foo{'bar'}, and replace the name of the hash, not including the sigil, with the hashref:$$hash{'bar'}. Your%would only be used to dereference to the full hash, as in your each case, not just an element.More helpful hints at http://perlmonks.org/?node=References+quick+reference.
