Maybe, but as you say it's a "horrible hack", and since my motivation
was for some code cleanup it's just kind of a wash. Ie, if I do that,
than it's debatable how much better that is than:

final switch(foo)
{
case Foo.a:
    bool gotoB;
    final switch(bar)
    {
    case Bar.bar:
        gotoB = true;
        break;
    }
    if(gotoB) goto case Foo.b;
    break;

case Foo.b:
    break;
}

Depends which you have more hatred towards: verbosity or goto.

In my case, I ended up just converting the inner switch to an if/else
chain, which actually isn't too bad since my inner enum/switch only had
three cases, one of which was just an empty "break;".

Some sort of "goto outer.case Foo.b;" could be handy, but I suspected
there probably wasn't such a thing.
