Using c++ operators as slots in Qt

I'm wondering if it is possible (and how) to use c++ operators, for example (), [] as Qt slots.

It seems that the compiler is complaining about this simple code

class MainWindowDecorator : public QObject
{  Q_OBJECT
private:
//some variables

public slots:
    int operator[](int i)
    {
    return i;
    }
}

The error is the following:

Error: Not a signal or slot declaration

You can create slot wrapper that would call dedicated operator.

The problem is that moc parser disallows that definition, probably because it expects an identifier and not a keyword.
