[armedbear-devel] Bug in metaclass support
Hello, this piece of code produces an error: (defclass foo () () (:METACLASS STANDARD-CLASS) (:DOCUMENTATION "bar")) condition of type PROGRAM-ERROR: Invalid initarg :DOCUMENTATION while it works perfectly fine without :metaclass, presumably because make-instance is not called to create the class metaobject. On class redefinition (say, I define foo without :documentation, and redefine it with it), it gives no error. This breaks Cells which always puts in a :metaclass option even when superfluous. Bye, Alessio

I should have mailed the list earlier, but this bug was fixed in trunk a few days ago. Bye, Erik
