Hi, Alan,
I can see that your suggestion will work. The key, as I understand it, is
the embedding of functions, thus:
(fix-ize (fix-ou word)))
which is indeed a Lisp-y way of doing things. It seems imperatively I miss
elegant one-liners such as this.
I'm right now close to getting Laurent's approach to work.
Thanks much for your help.
