is possible to cast hash to array in perl but without using further variable ?
This works as expected but another variable (@arr) is used:

perl -wlae '%hash=(name=>"linus", forename=>"torvalds "); @arr=%hash; print "@arr"'

I have tried those but neither worked (BTW what do they do ?):

perl -wlae '%hash=(name=>"linus", forename=>"torvalds "); print "@hash"'
perl -wlae '%hash=(name=>"linus", forename=>"torvalds "); print "%@hash"'
perl -wlae '%hash=(name=>"linus", forename=>"torvalds "); print "@%hash"'

    perl -wlae '%hash=(name=>"linus", forename=>"torvalds "); print (%hash);'

    Putting an expression in parentheses evaluates it in a list context, just like assigning to a list variable does.

    In the case of print, this casting is unnecessary, since it uses list context for both arrays and hashes. But if you want to do other array-style things with a hash, you can use this, e.g.

    $first = (%hash)[0];
echo $first;
