> I said this in another thread too, but the problem with Lisp is that it's sorta bundled with Emacs, so if you want to use LISP's powerful REPL you really have no choice other than learning Emacs.

You can use Medley which is Interlisp-D, a different, parallel strain of Lisp, a descendent of MACLISP, itself an ur-lisp ancestor of Interlisp, emacs lisp (older than EMACS, which didn’t start out as a lisp program at all), CommonLisp, Multics MACLISP and that even begat Scheme.

Interlisp didn’t even keep its code as text files (though I wrote an eMacs for it at PARC back in the early 80s) so you may find it more accessible.
