QString's arg() method has many overloads. Two of them are:

QString arg(int a, int fieldWidth = 0, int base = 10, QChar fillChar = QLatin1Char(' ')) const;
QString arg(Args &&... args) const;

In the following function, the compiler uses the first overload but I need the second one.

QString myformat(int num1,int num2){
    return QString{"%1 %2"}.arg(num1,num2);
}

I've tried casting num1 and num2 to l/r references and that does not work. I know I can use successive arg() or asprintf(). But how to force the overload resolution?
