;;; 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
;; - http://common-lisp.net/project/slime/
