Right, in both approaches you can choose to handle the error by ignoring it and crashing. In "errors as values" languages you have to make that choice explicit by marking the line with `unwrap`. Saying that this requirement is "the single most unproductive mis-feature a language could have" is extreme hyperbole, no? Adding `unwrap`s during development to imitate implicit exceptions for fast prototyping takes no time or thought at all.

On the contrary, when you later want to polish your program for release these explicit markings make it very easy to find the points in your code where errors can occur and which you don't properly handle yet.

Okay, if there's a simple way to mark some code as "compile this even if it's wrong", it's only a minor annoyance.

But the commenter I responded to seemed to me to be wishing for a language that explicitly disallows that. Maybe I misunderstood?
