Walter's answer to that has put me to silence for good. "But I use
fall-through all the time!" I then knew the feature will never make it.
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;
}
That way I can always tell when I read again the code wether this was
intentional or not. It wouldn't hurt at all if that "fallthrough"
comment became a keyword:
switch (c) {
case 1:
blah();
break;
case 2:
blah();
fallthrough;
case 3:
blah();
break;
}
Now the intent is clear even for the compiler.
