You forgot to remove one of the two braces on the right :-) 
   print "3",  keys(%{$termservers{$­key}}), "\n";

should be this:

   print "3",  keys(%{$termservers{$­key}), "\n";

    No. There are supposed to be two close-braces and one close-parenthesis. Let me spell it out: 
    keys(                  # take the keys of a hash
   %{                  # dereference a hashref
      $termservers{    # hash-table lookup
         $keys
      }                # END hash-table lookup
   }                   # END hash dereference
)                      # END keys(

      Sorry, obviously my mistake. Saw that immediately when I just looked at it again :-(

        No, that's cool. I actually should have spelled it out like that in my original reply... would have been more demonstrative of the issue to the original poster.
