A quirky multi keyed hash with an anon array for its value.
%modhash = ();
$modhash{ 'first:second:third' } = [ 'bob', 'bill', 'bo' ];
$modhash{ 'Canada:USA:China' } =
                               [ 'beaver','eagle','Mao' ];

# two sample entries, notice the anonymous arrays

foreach $key ( keys %modhash )
{
  @subkeys = split( /:/, $key );
  for( $i = 0; $i < scalar @subkeys; $i++ )
  {
    print "subkey-> $subkeys[$i]\t",
          "subvalue-> $modhash{$key}->[$i]\n";
  }
  print "\n"; # separates different main keys
}

Produces:
subkey-> Canada subvalue-> beaver
subkey-> USA subvalue-> eagle
subkey-> China subvalue-> Mao

subkey-> first subvalue-> bob
subkey-> second subvalue-> bill
subkey-> third subvalue-> bo

This is a snippet I came up with as a response for
someone's weird post. Its pretty useless, but I have
a feeling someone, somewhere, is going to use it.
Perhaps its good practice for me ( or you ) to make
a module for it.
