Could you show an example of such scenario? I don't get it.
Having a set of bit flags, and adding another bit flag later, and
failing to account for that in existing switch statements.
auto bit_flag = ...;
switch(bit_flag) {
case old_bit_flag_1:
// do something
break;
case old_bit_flag_2:
// do something
break;
default:
break;
}
Now suppose bit_flag can get an additional "new_bit_flag" value. How
does "default" helps me notice that I'm supposed to add it to that
switch statement?
I still can't see your point :-(
Maybe I need some more example code to understand it.
