Works for me on the elephant-1.0 repository. You have to indicate in
the base class that subclasses will inherit its index. Then you do
get-instances-by-value/range on any class on the inherited slotname to
get all instances inheriting from the base.

Thanks, that's good code.

This is O/S-specific, I think. I think DLL loading is always eager
while SO loading is not, something like that. So maybe SBCL FFI
is missing some workaround that other L

yep, sort of.. but i think Ian's approach is "good enough" since
rarely people need both superclass and subclass lookups to
be fast enough.
but i'll probably

Can you confirm that UFFI on win32/SBCL works in other cases?
Can you find the alien by using SBCL's FFI directly?

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.

Yes, definitely.
