Does elisp have a way to jump to (goto) labels in the code, ala common lisp's go?

Question

 (tagbody
   (setq val 2)
   (go lp)
   (incf val 3)
   lp (incf val 4)) =>  NIL
 val =>  6

PS: This is a question about control flow, not jumping to locations in files.

The `cl-lib` library offers `cl-tagbody` (and, I presume, friends), which offers some of the common lisp primitives to do this sort of thing. — Dan, Sep 22 '21 at 16:03

It works exactly the same, we just need to use cl-tagbody instead.

(cl-tagbody
 (setq val 2)
 (go lp)
 (incf val 3)
 lp (incf val 4))

val
