Dear Erik,
Based on your input, I have been thinking more about making my interface case sensitive. It would be better. After doing a little research I tried:
(setf (readtable-case *readtable*) :invert)
This seems to have made all the standard stuff ("car, cons, etc.") lowercase as I'd prefer. After that I tried creating lists:
(setq x '(HELLO There how))
and the case seems to be preserved - not inverted.
I also tried things like:
(defun fun (x) (+ 1 x)) (defun Fun (x) (+ 2 x)) (defun FUN (x) (+ 3 x))
And it worked as expected. I'm a bit confused. Why aren't symbols (as in '(HELLO There how)) inverted? (I understand that :invert doesn't change case on mixed case symbols but then all upper or all lower should be inverted.) Is *print-case* being affected?
At first test, it seems like :invert does exactly what most people want - case sensitive lisp that has system symbols all lower case. Are there instances in which this doesn't work? Will this affect lisp-java usage when it comes to case?
Any pointers would be appreciated.
Thanks.
