This is close, though it only permits values at leaves and stores the
values in the reverse order. Depending on what you need, this might be
sufficient:
(defn insert [container letters value]
(update-in container letters #(conj % value)))
e.g. (-> {} (insert "foo" 3) (insert "foo" 4) (insert "bar" 7))
If you do need values at non-leaf notes, you just need a slightly more
sophisticated representation.
