If you mean you are looking for a finalizer interface similar to what
Common Lisp's trivial-garbarge library provides, there was one in
Emacs Lisp before `make-finalizer' was provided.

Both that one and trivial-garbarge are based on weak references.
However that is actually not very good because that impose a lot of
jobs on GC, at least for Emacs the garbage collector is not as good as
many Common Lisp's ones.
