Yep Rust approach won. Pretty much every new language is adopting Result style errors and it's been adapted to plenty of existing languages.

It's a product of functional programming, and for me I can't see how you would ever want to handle errors outside of the functional programming railway-oriented style. For me it's just superior.

Umm, actually, it's specifically a coproduct of functional programming. ;-)
