I want to know how to write correct patches in the futures. How do we notice in tests if we get something like this wrong?

You'll see these if you set the JSC_validateExceptionChecks environment variable to 1 or "true". WKTR might need __XPC_JSC_validateExceptionChecks, though. 

That said, I think only JSC runs tests with this option since WebCore has so many false positives i.e not releasing the scope before tail-calling like here. At some point we should sit down and fix those...

You'll also need a Debug or Release-Assert build.
