[It would be nice to have the whole relevant description in the repository, as part of the commit, instead of citing some website which may or may not be offline]
I believe this patch would break the following use case which used to work earlier
$ cat test.l (in-package "CL-USER") (eval-when (load eval compile) (when (find-package "FOO-PACKAGE") (delete-package "FOO-PACKAGE")) (when (find-package "BAR-PACKAGE") (delete-package "BAR-PACKAGE"))) (defpackage "FOO-PACKAGE" (:export "BAR-SYMBOL")) (defpackage "BAR-PACKAGE") (eval-when (load eval compile) (unintern 'foo-package:bar-symbol "FOO-PACKAGE"))
(assert (not (find-symbol "BAR-SYMBOL" "FOO-PACKAGE")))
* (load (compile-file "test.l")) It breaks non-standard code, that is right.
