Rust does "errors as values" pretty well, see [1]. You can manually handle them if you want, or just apply the '?' operator to auto-propagate them out of the function. In both cases, it is obvious that there was an error handling needed.

I didn't know that! Every time I hear about Rust my opinion of it grows brighter. Thanks for sharing this!
