;; `make-uuid-from-string' as we currently have between

;;
;; :NOTE What about `cl:read-from-string' instead of `cl:parse-integer' e.g.:
;; (let ((*read-base* 16)) (read-from-string "88"))
;; No. When asked on #lisp noting that the bounds fo string and its contents are
;; known and pre-verified to be all hexadecimal chars -- nyef says:
;; ,----
;; | Use PARSE-INTEGER. It's more efficient, and makes an explicit
