Closest thing to a real interblock branch without braces, IMO, is `break` and `continue`, but those are both at least lone statements, not expressions. It "looks like" control flow. Personally, I don't count `return`, I view it as it's own thing from a logical standpoint. Obviously if we were talking about literal CPU doing a jump, well then a lot of things would count, but that's not what I mean in the frame of structured control flow and more in the realm of implementation details.
I could have sworn that like most modern languages Go has `break label` although being statement oriented it doesn't have `break label value`.
