There is an :inherit slot keyword option for indexed slots. It causes subclasses of the defining class to share the index of the base class. You can inhibit subclass sharing by re-defining the slot in the base class. I found a bug in unstable and patched it so this works again.</blockquote>

Calling map-inverted-index (and the top-level API fn's get-instances-by-value/range) from the base or subclasses will return instances for all classes that share that base index. We could add some refinements such as mapping from a subclass filters out any superclass instances during the traversal.<br>
<br>
We can easily add a keyword arg to map-class and get-instances-by-class to return all subclass instances as well.<br><font color="#888888">
