precedence list in all basic classes and tests for eqv? and
equal?.
* goops.scm (compute-getters-n-setters): Check for bad init-thunk.
(eqv?): Added default method.
(equal?): New default method which uses eqv?.
* eq.c (scm_eqv_p): Turned into a primitive generic.
update and active slots.
* goops.scm (compute-getter-method): For custom getter: Check
boundness even if there is an init-thunk. (The getter can return
#<unbound> even if the slot has been set before.)
(remove-class-accessors!): Also remove accessor-method from its
accessor.
* goops.c (scm_sys_fast_slot_ref): Use SCM_SLOT instead of
scm_at_assert_bound_ref. (We don't want the unbound check. See
oop/goops/active-slot.scm.)
define-generic and define-accessor will continue to work when
mmacros are expanded before execution.
* test-suite/tests/goops.test: Added tests for define-generic and
define-accessor.
