I do not like it at all ;-( (GV)

I would go for this :

switch(hugo)
{
    case HUGO0:     
        doSomethingCool();
        break;

    case HUGO1:     
    {
        UInt32 tempint = getTempInt();
        doSomethingCooler(tempint);
    }
    break;

    case HUGO2:     
        veryShort();   
        break;

    case HUGO3:     
        veryShort2();  
        break;

    default:        
        nothingCoolToDo();
        break;
}

typedef MyClass::HelperClass HelperClass;

switch(hugo)
{
    case HelperClass::HUGO0:
    {
        doSomethingVeryCoolWithUnsuspectingClass(
            this->getUnsuspectingClass());
    }
    break;

    case HelperClass::HUGO1:
    {
        UnsuspectingClass & victim = this->getUnsuspectingClass();
        suspectClassInstance->makeInconspicious(victim, 
                                                HelperClass::NOW);
    }
    break;
 
    default:
    break;
}
