The BoundMethodMember specialization for the void return type is only
needed to avoid accessing the ret_ member variable that is lacking from
the corresponding BoundMethodPack specialization. By adding a
BoundMethodPack::returnValue() function to read the member variable, we
can remove the complete BoundMethodMember specialization.
