I agree. Especially as someone that likes LISP-like languages and uses Janet and Fennel quite a bit (and some elisp, in the past also Clojure) but never used a macro for anything. Would love to hear more about that third dimension I am missing out on.

Marcos are only very appealing to tyros. Most old salt Lispers avoid them. I would argue that a macro is only appropriate if you are adding a genuine syntactic feature to a language (one hint that this is the case is if your macro involves binding variables).

Ditto.
