Well, to be more precise, it doesn't allow fallthrough when the case statement contains code. It will allow it when it doesn't. e.g. case 0: case 1: break; is perfectly legal. However, when the case statement contains code, then yeah, some form of control statement is required to exit the case statement, but that's a lot more than just break. continue, goto, return, etc. can all be used to exit a case statement. Any control statement that explicitly exits the case statement will work. And of course, goto case can be used for explicit fallthrough. - Jonathan M Davis
