I found myself wanting to reference the finalized object from a finalizer, so I added this wrapper around trivial-garbage:finalize, using a weak pointer to avoid permanently referencing the object from the finalizer closure.

Which Lisp are you using. IIRC, some (most?) Lisps run finalizers /after/ the object's memory is reclaimed, in which case the weak pointer will be null.
