They have introspection but not a macro language; macro languages have been written using introspection. I believe that LISP was the first to have introspection.

Ada, Go, Java, Perl, Python, Ruby, Raku (Perl > 6), Rust, etc., lack metalanguages. One might argue that Python and Ruby (at least, I’m not familiar enough with some of the others to say) are their own metalanguages. You can use things like metaclasses and decorators to dynamically generate a fair amount of code. I’ve noticed no one has mentioned Lisp in this discussion. -- Pew, Curtis G curtis....@austin.utexas.edu ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
