I'm LISP novice (although met it some 15 years ago, now I'm more serious
with our relationship at our second attempt :) :)
so I can be easily wrong
but my vision of your BEGIN block is:
(eval-when :when-compile
(dolist (fname '(BUFFER CALLBACK ETCETERA))
(eval (read-from-string (format nil "(defun ~A ()
(do-something-useful))" fname)))))
Why didn't you placed functions in AUTOLOAD, and creating them only when
needed?
My Tcl::Tk module do heavy usage of AUTOLOADing, you may want to look at
the approach :)
Initially I did "eval $string" but then come to safer approach.
PS. now this *is* off-topic, sorry for that.
I'll try to be more on-topic from now on :)
