That's being too smart. And I don't think the bytecode compiler can do
the lifetime analaysis right now. It is possible that this could be
changed in future releases of Emacs.

You would only need finalizers for complex objects, so ideally you
could use OOP to manage that, probably EIEIO but not limited to that,
and you may even come up with your own.
