A good reason would be that you care about identity equality and not value equality. You care that the key is the exact same instance, not that it is an equivalent instance. (== vs isEqual:) Another reason would be that the keys might not implement NSCopying, which NSDictionary requires.
But couldn't you just do that with an NSArray instead of an NSDictionary, using -indexOfObjectIdenticalTo: and such?
