nostr:npub1dtw0ve3yrtslcda2l46lmm7t5z7m7sc6xf9r7cd98e37pd92utdsd885ra You probably have to get all the keys first:

(defun hash-table-keys (hash-table)
  (let ((keys ()))
    (maphash (lambda (k v) (push k keys)) hash-table)
    keys))


and then run your own iteration. You are right, hash tables are not a first class citizen in Elisp, unfortunately.
