As a consolation, + however, the SBCL implementation of these functions now calls + REINITIALIZE-INSTANCE as specified by AMOP. + * bug fix: slot-definition documentation is propagated as per ANSI + 7.6.2 to EFFECTIVE-SLOT-DEFINITIONS. + COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION + argument, as do eslotd initialization methods.
