This is actually one example I'd like to refer to when people are talking that alternative languages with macros can achieve Lisp's flexibility: https://www.pvk.ca/Blog/2014/08/16/how-to-define-new-intrinsics-in-sbcl/ https://www.pvk.ca/Blog/2014/08/16/how-to-define-new-intrins... Till this point I haven't seen anything similar in languages other than Lisp. Maybe Elixir can do this but I lack enough knowledge to judge. BTW: that does not mean I'm a Lisp zealot, been there but has been away for quite some time.
