Vectors and maps are already functions of their indices and keys, respectively. I don't really think it makes sense for other sequence types (seqs, lists, etc.) because they aren't naturally associative in the same way. Finally, there isn't a Clojure form I'm aware of that allows negative indices in the same way eg Python does, but I for one would find that incredibly useful.
