+ consistent, even on internal alternate-metaclass objects.
+ * bug fix: SB-MOP:FUNCALLABLE-STANDARD-OBJECT is now a subclass of
+ STANDARD-OBJECT, as required by AMOP.
+ * bug fix: the classes STANDARD-CLASS and
+ SB-MOP:FUNCALLABLE-STANDARD-CLASS are now compatible in the
+ SB-MOP:VALIDATE-SUPERCLASS sense; there remains a constraint about
+ finalized classes and the FUNCTION class.
+ * bug fix: the SB-MOP:METAOBJECT class is now implemented as
+ specified by AMOP.
+ * bug fix: flush closure information collected by physical
+ environment analysis prepass before the main pass. (bug reported
