@screwlisp indeed. But Medley is also not a pure InterLisp, and it lost something very significant in the change – namely, the structure editor. It cannot be impossible to add the structure editor back in, and by now someone must have done it. But for people used to InterLisp, and especially for me having come from Portable Standard Lisp, that was a very big loss.

Using a text editor to edit #Lisp still feels Just Wrong.
