Even using `rx-define' is not so helpful (its expanding mechanism is
different from e.g. defmacro):

#+begin_src emacs-lisp
  (rx-define any-char (&rest string) (regex (concat "[" string "]")))
  (rx-define not-any-char (&rest string) (regex (concat "[^" string "]")))
#+end_src

Will not work inside `not'.  Thus two definitions.

Ok, in the end I could not really help at all...

Michael.
