Greetings,

Given a file name ff.lisp containing the following:

(setf (readtable-case *readtable*) :invert)

(defpackage "abc" (:use "COMMON-LISP") (:export "MYFUN")) (in-package "abc")

(defun myfun (a b) (+ a b))

; EOF

Then try:

(use-package "abc") (myfun 4 5) (abc:myfun 4 5) ; this should not work (ABC:myfun 4 5) ; this should work

This works as described in sbcl, cmucl, clisp and ecl but doesn't work in abcl. It seams abcl takes into account the case of the entire "ABCL:myfun" when dealing with case. All the other lisps treat "ABC" and "myfun" separately in terms of string case.
