Hi everyone, I'm creating a script that build node tree (using HASH ref) After i've done using the tree, i want to deallocate the nodes. should i traverse through all the nodes and use 
sub deletenode
{
   $node = shift;
   if ($node->{'child'}) {
     foreach ($node->{'child'}) {
        deletenode($_);
     }
   }
   else {
     $node = {};  
   }
}

[download]
or simply delete the tree (assume all the nodes are automatically recovered)? 
$tree = {};

thanks in advance :)
