It's not necessarily a "re-"throw. It could just be a throw of a newly detected error, like:

    try {
        if bad_thing {
            do yeet Error::new(...);
        }
        carry_on()
    }

Just plain "throw" would probably be fine, but I understand not wanting to bikeshed it at this stage.

Weirdly, "yeet" really does convey the sense of "just give up and chuck this thing back instead" that makes it a reasonable nice converse of "try", i.e. "try { yeet }".
