1. eval the following
(let ((c 10))
(cl-tagbody :next
(cl-tagbody :next
(print c)
(cl-decf c)
(when (zerop (mod c 2))
(go :next)))
(unless (<= c 0)
(go :next))))
2. if: No catch for tag: #:cl--tagbody-tag, :next
Additionally eval the following
(let ((c 10))
(cl-tagbody :next1
(cl-tagbody :next2
(print c)
(cl-decf c)
(when (zerop (mod c 2))
(go :next2)))
(unless (<= c 0)
(go :next1))))
Error: cond: No catch for tag: #:cl--tagbody-tag, cl--exit
