That's really ugly. It also gets twice as ugly if you have to use a static if.

Sometimes you have to call specific code for each of these cases, but then
follow them with a generic call. So you use a goto to a single label. At the
point of the label you won't know what the switch value is unless you stored it
somewhere, e.g. (pseudocode):

void main()
{
    switch (auto x = get)
    {
        case "a": handleA(); goto common;
        case "b": handleB(); goto common;
        case "c": handleC(); goto common;
        common: log_output(x); break;

        default:
    }
}
