AFAIK assert(0) and other falsey assert have a special meaning 
for compiler.
So probably it's not so hacky but just a way to say that case 
can't happen.

It is used also for:


auto myfunc(int i)
{

    if (i == 0) return 10;
    else if (i == 1) return 3;

    assert(0);
}

And also with non final switch using

switch(var)
{
    case ...
...
    default: assert(0);
}
