When applied to a transient map, adds mapping of key(s) to
val(s). When applied to a transient vector, sets the val at index.
Note - index must be <= (count vector). Returns coll.

(defn assoc!
  ([tcoll key val]
    (-assoc! tcoll key val))
  ([tcoll key val & kvs]
    (let [ntcoll (-assoc! tcoll key val)]
      (if kvs
        (recur ntcoll (first kvs) (second kvs) (nnext kvs))
        ntcoll))))
