Switch Statement Fall-Through

[August Nagro]

Hi!

I recently read Stephen Colebourne’s blog on the new switch syntax (https://blog.joda.org/2019/11/java-switch-4-wrongs-dont-make-right.html), and although I don’t agree with the proposed solution, his issue with the new switch falling-through is spot-on.

I've personally used fall-through switch statements, but I think they should only ever be applicable to the old-style switch. Having the compiler enforce this will prevent a lot of misuse and confusion. Instead of four types of switch, there is only two:

1. switch with only ->, that doesn't fall-through, checks exhaustiveness, has yield, commas between cases, and can be used as an expression.
2. switch with only :, the standard switch.

Sincerely,

August Nagro
