[ But at least, now I understand what you meant by the fact that the behavior depends on the byte-compiler's analysis. ] In any case, I don't think we have much experience with the current `make-finalizer` API (nor with other finalizer APIs) in ELisp, so I think there's room for tweaks/changes. But it should be based on concrete cases in real world ELisp code. Stefan
