> auto-bubbles up if not handled

I'm guessing you already know this, but for anybody else reading - this isn't entirely accurate; Result::Err doesn't auto bubble up like an exception, you have to manually bubble it up. The "special sauce" comes from (A) the compiler forcing you to notice this and do something about it, and (B) the `?` syntactic sugar to make that super easy.

It does occur to me as I'm typing this that you might be talking about panics, though, in which case yeah that's entirely accurate.
