--- Comment #2 from deadalnix <[email protected]> --- `__os2` can only be false if no exception was thrown. There is no reason to emit any exception handling code in such function, even in the instances where the bound check might fail. In fact, the whole point of scope success is "run this when the scope is exited using regular control flow rather than exception handling", so there is no reason to emit any exception handling code ever when dealing with scope(success). --
