 ;;; Commentary:
 
 ;;; Support for evaluating Common Lisp code, relies on SLY or SLIME
 ;;; for all eval.
 
 ;;; Requirements:
 
 ;; Requires SLY (Sylvester the Cat's Common Lisp IDE) or SLIME
 ;; (Superior Lisp Interaction Mode for Emacs).  See:
 ;; - https://github.com/capitaomorte/sly
 ;; - https://common-lisp.net/project/slime/
