<div dir="ltr">I reasoned that *sometime* people have to upgrade emacs and we can't support to many old versions, after all Emacs 19.29 is not new. :-) Of course there is no practical difference in doing the expansions "by hand" or leaving it to emacs as the macros are so simple.<br>

Hi,<br>
My original intention was the same, but the new style backqoutes was<br>
introduced in Emacs 19.29,<br>
( <a href="http://www.gnu.org/software/emacs/elisp/html_node/Backquote.html" target="_blank">http://www.gnu.org/software/emacs/elisp/html_node/Backquote.html</a> )<br>
and erlang.el contains compatibility workarounds for Emacs 18:<br>
<br>
;;; Avoid errors while compiling this file.<br>
<br>
;; `eval-when-compile' is not defined in Emacs 18. We define it as a<br>
;; no-op.<br>
(or (fboundp 'eval-when-compile)<br>
(defmacro eval-when-compile (&rest rest) nil))<br>
<br>
Replacing the old style backquotes whith new style ones would break<br>
compatibility with Emacs 18, so i just expanded them.<br>
<br>
Regards,<br>
Balint<br>
