Now, what I would have expected you to say when you found the `uniq()`

both be `NULL`...
Nah, you are expecting too much out of me. I didn't ask because I
knew we didn't need to, and I didn't particularly care if you lucked
out or if you had the same understanding as I had how you arrived at
the right solution ;-)
