Thr only reason this works in other languages is because they’ve made the choice to return objects that represent success+value or error and then added explicit syntax to support those types. That means function signatures put the error in the return type instead of a separate exception channel, but that’s really only a syntactic difference. It’s otherwise isomorphic.
