The CLOS code is split between Java and Lisp, so we need to analyze further: we'll keep you posted.
Thanks for the report!
BTW, my name is Verna, not Verner :-) So, after some discussion on cll and pro@, I have some precisions about this. From what I understand of CLHS now, an implementation is not required to initialize a shared slot at class creation time from the initform (so far so good for ABCL). However, the iniform of a shared slot must be evaluated in the dynamic environment of the defclass call, even if it's not used to initialize the slot right now (see the defclass page). The following test shows that ABCL's behavior is currently incorrect in that regard: (defclass fungy () ((x :allocation :class :initform (progn (format *debug-io* "~&x initform~%") 6) :initarg :x) (y :initform (progn (format *debug-io* "~&y initform~%") 7) :initarg :y))) CL-USER(1): (defclass fungy () ...) #<STANDARD-CLASS FUNGY {1AEE513}> CL-USER(2): (make-instance 'fungy) x initform <========= this is too late y initform #<FUNGY {18C2354}> -- Resistance is futile.
