PPS: Anton reports no error. Is that because the classes that are broken are never invoked during the loading of those libraries, only during the using of them, but no code in quicklisp actually uses them?
Maybe there are no such classes? Why would people extend operation?
As for signalling the problem, I agree with Robert in the sense that if such users exists, it is friendly to save them from debugging an issue like this.
If not error, then at least very very bold warning, or cerror
