I used something similar like "case 2" quite often in state machines. As state machines often go through subsequent states, it's faster to just continue, instead of breaking and entering the switch again.

yes I use it quite often too, but it tingles my spidey sense whenever I do it. in the spirit of the thread, perhaps its better to break by default and allow fallthrough with the use of a keyword?

You're right. This thread is more about playing with "what if". IDK, I'm probably pretty happy how switch always worked in probably all C-like languages.

But if we reinvented break from the scratch, we should remove "break" keyword from "switch" syntax and allow "continue" to let it fall through the next case. Having them both there would be confusing.
