Hum two suggestions. Sometime I want fall-through when I write a
switch, but I always make it clear that it isn't a bug by writing the
intent in a short comment:
switch (c) {
case 1:
blah();
break;
case 2:
blah();
// fallthrough
case 3:
blah();
break;
}
I just use whitespace:
switch (c) {
case 1:
blah();
break;
case 2:
blah();
case 3:
blah();
break;
}
Works fine.
No whitespace works fine, too. I strongly advise requiring control flow
at the end of the break. Your style notwithstanding, fall through *is*
rare. It is also more brittle than goto case xxx; because it is not
invariant to manual code motion. It does make sense to write more to
achieve the more dangerous and less used result, than the other way around.
