Thanks.  But then I would need to do the following:

+ cl-mapcar -> seq-mapn
+ cl-labels -> named-let (right?)
+ cl-letf* -> What?  unwind-protect?

Suggestions appreciated.

Done.

Done.  IIRC, Emacs indented the code as the following when I wrote it:

--8<---------------cut here---------------start------------->8---
    (cl-labels ((call-decorators (fns)
                                 (with-selected-window current-window
                                   (if fns
                                       (funcall (car fns) windows
--8<---------------cut here---------------end--------------->8---

So I placed the argument list on its own line.

I don't think so.  I don't know why I wrote that, but looks like the
code is same as (progn (redraw-display) tree).  Changed.

I was using Emacs 27 back then, hence that comment.  Now I changed that.
Anyway, is there any benefit that new primitive?

Nice idea.  Done.

Hmm, tail call optimization, interesting.
