I don’t think I’ve seen it specifically mentioned when I skimmed the thread, but I typically write functions that can raise as very thin wrappers around the versions that return either ok-tuples or error-tuples. It just calls the non-raising version directly, then unwraps the okay tuple or raises on an error tuple. Exceptions generally don’t need all of the context an error tuple might include, so it’s rare that I need to have two parallel, standalone function bodies, which need better test scrutiny.
