Consider this:

int process(int d)
{
   switch (d)
   {
      case 0: return process_0();
      default: THROW("unexpected argument");
   }
}

As long as THROW maps to 'throw' all is fine, but for anything else the compiler
might find that you fall through the switch block and thus issues a 'missing
return statement' warning/error.
