 But even without these additional mechanisms, exception checking is already useful as it is. It gives a clear path forward to make code that uses exceptions safer, better documented, and easier to refactor. The only loophole arises for scoped abilities - here we have to verify manually that these abilities do not escape. Specifically, a `try` always has to be placed in the same computation stage as the throws that it enables.
 
-Put another way: If the status quo is 0% static checking since 100% is too painful, then an alternative that gives you to 95% static checking with great ergonomics looks like a win. And we might still get to 100% in the future.
