[armedbear-devel] Read tables

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.
