...which is probably pointless since hash keys are guaranteed to be unique.

Which doesn't stop him comparing them. He might be interested to see if one is a substring of the other, or maybe all the keys are numbers, and he wants to compare them to see which ones are bigger or smaller...

Huh? I was almost following you until you got to that last part.

I'm guessing a bit here, but I think he doesn't want to compare the keys if one key already "contains" the other key. Still fairly easy to do though.
