I believe that class slots should be initialized in finalize-inheritance the latest, and not only in shared-initialize on instances, to be useful for such scenarios. (But it's fine if you disagree, then I have to live with that and find a different solution…)
I'm a bit slow with the fixes these days, but this should now be implemented in r14153.
Note that the related form
(defclass test ()
((slot :initarg :slot :allocation :class))
(:default-initargs :slot 42))
currently still has the old behavior (unbound slot until the first instance is created). Do you think this should be fixed as well?
