I guess I don't quite understand what you are trying to do. From your desc,
all you stated is you wanted to know how many unique items you have. SO parker:san,
bowen:san, is san only once in the hash. Or are you combining the data as in
Parker:san is the key. You only need pairs if you are trying to reload a hash. SO,
you can pull san and check as in :
$SAN{$MyKey}++ where $Mykey is san or Parker:san. To see what you have:
foreach my $MySortKey (sort keys %SAN) {
print $MySortKey . "\n";
}
