Hello,

The following in SBCL 2.1.11 produces 3, which I expected.

     (loop for i in '(1 2 3)
           for j from 1
           finally (return j))

The following in Emacs 29 produces 4, which I did not expect.

     (cl-loop for i in '(1 2 3)
              for j from 1
              finally (cl-return j))

This is a simplified example that only shows the difference.

I don't know what the standard behavior is, but I personally believe=20
that the SBCL output makes more sense.

Thank you.

I get the same result with SBCL 2.4.5.

I also get 4 with Emacs built from master.

FWIW, GNU CLISP 2.49.93+ (built from the git repo) returns 4, not 3, for
the above Common Lisp loop sexp.

The CLHS section 6.1.7.2 says

"The finally construct causes the supplied compound-forms to be
evaluated in the loop epilogue *after* normal iteration terminates."
(emphasis mine).

To me that means all bets are off regarding the values of variables
created in the context of the loop iteration. But we should ask a
Common Lisp expert to be sure.
