I concur with Ovid on srawls' solution: very slick indeed.

The reason I'm trying to get at a scalar value for the subkeys
in a %HashOfHashes without looping is because I'm already
iterating through the keys/subkeys.

What I'm really trying to do: given a %HoH, iterate through
the subkeys and display each $interval group of subkeys
(where $interval is a positive integer). Of course, when
I get to the end, I'll need to kick out the last group even
though the counter never gets to $interval.

Example and pseudocode: my %HoH contains 97 subkey-value pairs
(but I don't it's 97). 

$interval = 10;
foreach $key (keys %HoH) {
  if ($interval % $counter == 0) {
    display(\%tmp);
    $counter = 0; # reset the counter
  }

  foreach $subkey (keys %{$HoH{$key}}) {
    $tmp{++$counter} = "$key -- $subkey";
  }
}

The problem I run into is when $counter is a remainderless
divisor of $interval (ie, $counter = 1). I can kludge around
this obstacle by doing a sort of --$secondary_counter decrement
if I knew the total number of subkeys with which I could compare
$secondary_counter. This is where srawls' golfing looks great
but then I'd be iterating over the hash twice.
