Re: Supplying DOC string in a `defun' using `defvar'

[Robert Thorpe]

I tried this example out.  In a emacs-lisp-mode buffer I put the following:

(setq lexical-binding t)

(defvar my-doc "foobar")

(defun my-fun (x)
  (:documentation my-doc)
  (+ x 42))

I evaluated each of them in turn.  After that when I do C-h f on my-fun
I get "foobar".  What is a little strange is that Emacs tells me that
my-fun is a "Lisp closure".

If I *don't* have the first line (the lexical-binding one) then this
doesn't work.  In that case C-h f tells me that my-fun is a "Lisp
function" and has no documentation.
