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?
