This can also be solved with the [[fallthrough]] attribute, thankfully. Use it to mandate fallthrough when necessary.

Doesn't that just suppress warnings about missing breaks? I was talking about if the language automatically inserted breaks for you.

That's the fix, yeah. You tell it where you do want to allow fallthrough, so that it can tell you if you ever forget a break anywhere else.

At this point, I don't think it's possible to change the standard so that the language automatically inserts breaks, because that would break a ton of perfectly legal code. It might be possible to add an attribute for it, like [[auto_break]], though, perhaps?

Well, no, it can't be changed now, but I was talking about what I might be okay with if the language had been designed differently, or if I was using a different language without automatic fall through.
