We had a very very experimental branch with it, using backtrace first, then unwind. But it is not suggested, not performant. It's far from the correct desired implementation, for which Mathieu could give more details.

It works, but not to be used in production. Students have used it in the lab for some specific use case prototyping. I won't share the branch here, but if you wish to try, let me know.
