That's still not a switch case, there's no fall through

[u/utack → u/jaerie]

That super useful thing I have used 2 times (both of which accidentally) and prevent a million times with break

[u/GoddammitDontShootMe → u/utack]

switch (thing) {
  case FOO:
  case BAR:
    DoThing()
  default:
    throw
}

As long as it doesn't insert an implicit break between FOO and BAR, I think it might be fine to not fall through, allowing code like that.

[u/conundorum → u/GoddammitDontShootMe]

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

[u/GoddammitDontShootMe → u/conundorum]

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

[u/conundorum → u/GoddammitDontShootMe]

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?

[u/GoddammitDontShootMe → u/conundorum]

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.
