Not exactly. With this version, symbols generated with gensym are never
used, and the macro isn't hygienic anymore.
I still think your first take about this macro was the good one. I've
pushed something very similar. Could you verify if it is correct on the
compiling side?

Something along the lines of:
#+begin_src emacs-lisp
(progn
(defconst org-e-beamer-options-alist '(...)
"Alist between filters keywords and back-end specific filters.
See `org-export-filters-alist' for more information.")
(defvar org-e-beamer-translate-alist '(...)
"Alist between element or object types and translators."))
#+end_src

Could you paste the error reported by ERT? I can't think of any recent
change in this area.

It should be fixed.
Thank you.
