Description

The generic function slot-value-using-class implements the behavior of the slot-value function.

The implementation is as described in AMOP, except that the third argument is the slot name, and not a slot definition metaobject. The primary methods specialize on t for this argument.

Note: by default, standard slot accessors are optimized to not call slot-value-using-class. This can be overidden with the :optimize-slot-access class option. See defclass for details.
