That seems to work just fine... but I'm worried. I "guessed" at
using the key of "nil" since I want the actual objects in the array
to be the target for the @selector. Is it a fluke that this works?
I don't want to rely on undefined behavior.
Hmm. Good question. You could use @"description" as the key to
eliminate the uncertainty. Or maybe @"self".
Cheers,
