It uses thread_local raw pointers, one per error type. This is needed in
order to decouple result<T> from the static type of error objects being
propagated, which I consider critical, see
https://zajo.github.io/leaf/#rationale.

Is it compatible with coroutines or fibers or other non-thread-based stacks?

Good question. I'm not sure, but I'm interested to know what are the issues.
