Can you share a rust playground link with an example of what you are describing? I still don’t follow how a reference can extend the lifetime of some memory, even on the heap. Sounds like you are describing a language that uses reference counting to manage memory, and I’m not sure what purpose a borrow checker would serve in a reference counted language.
