I wasn't talking about requiring it in code review though. The OP didn't make an automatic linter that issued a warning when you did this implicitly, he removed the ability to do it entirely. With a linter, you can add a comment, like /* falls through */ to disable the lint warning. With the OP's change you can... use a series of if-else blocks? The alternative isn't listed, which is why I asked.

Sorry about your last company, though. Sounds like it was annoying to work there!
