For better or worse I think e-lisp is here to stay, with all its quirks. I think of it as "text processing Lisp", much as I think Perl is still a useful go-to for practical extraction and reporting. The world of other Lisps is rich and bountiful. I'm a secret Schemer myself and love Racket, but I'm not sure emacs needs re-writing in fresher dialects. What's the main case, does anyone know? It might be nice if e-lisp still had room to mature and incorporate some lessons from younger Lisps.
