body: <p>Experimental values on scalar is now forbidden in old software:</p>
  
  <pre><code>$link = Winners::Links-&gt;new();
  my @fields = $link-&gt;column_names;     
  foreach my $field ( values @fields[0]) {
  </code></pre>
  
  <p>I tried to make :</p>
  
  <pre><code> foreach my $field ( values {@fields[0]}) {
  
   foreach my $field ( values %{@fields[0]}) {
  
   foreach my $field ( values %@fields[0]) {
  </code></pre>
  
  <p>Non of them works. Any Idea how it should be done? Thx.</p>
  
  <p>Here is more on @fields object definition:</p>
  
  <pre><code>[[
    'id',
    'entry',
    'selection',
    'status'
  ]]
  </code></pre>
