reduce-kv different from clojure

[FalseProtagonist]

This fails in :lsp, works in :clj:

(reduce-kv (fn [acc i v] (-> acc (update :ks conj i) (update :vs conj v))) {:ks [] :vs []} [:a :b :c])

Confirmed. Probably just need to do a map-indexed or something over the vector for now. This will require implementing a few new interfaces to support k/v reducing.
